Owners Nissan Almera G15 with motors HR16DE (1.6 l) or K4M (1.6 l, Renault) often encounter a problem when the engine begins to “trouble” - twitch at idle, lose power or vibrate. Symptoms can appear both when cold and after warming up, and sometimes only under load. In 80% of cases, the problem is related to the ignition or fuel supply system, but there are also less obvious reasons that are not written about in standard manuals.

This article will help you figure out why the engine is misfiring Almera G15 (including restyled versions 2016–2022), how to carry out diagnostics without a scanner and what to do to fix the problem. We analyzed reviews from owners, data from forums (including Drive2 And Almera-Club), as well as technical bulletins Nissan - here are only proven solutions, not speculation.

1. Signs of engine tripping: how to accurately identify the problem

Tribbing is a malfunction of one or more cylinders, but its symptoms are often confused with other malfunctions. Here's how to accurately identify the problem on Almera G15:

  • 🔍 Vibration at idle - especially noticeable on the steering wheel or gearshift lever. On HR16DE The vibration often increases when the air conditioner is turned on.
  • 🚗 Dips during acceleration — the car “stumbles” when you press the gas, especially at speeds of 2000–3000 rpm.
  • 💡 Check Engine - may light up or flash. Error codes P0300–P0304 directly indicate misfire.
  • 🔊 Uneven exhaust sound — instead of a smooth “noise,” you hear popping or “mumbling,” especially when it’s cold.

On Almera G15 with Jatco gearbox (variator) tripping is often disguised as “twitching” of the box. To eliminate the CVT, check the behavior of the engine in neutral gear: if the vibration remains, the problem is in the engine.

⚠️ Attention: If tripling is accompanied white smoke from the exhaust pipe and a drop in antifreeze level - turn off the engine immediately! This is a sign of a burnt-out cylinder head gasket or a crack in the block, which HR16DE is fraught with water hammer.

2. Top 7 reasons for tripping on Nissan Almera G15

Analysis of data from diagnostic scanners (Launch X431, Autel) and service station reports show that on Almera G15 Troubling is most often caused by the following faults:

Reason Symptoms Difficulty of repair
1. Faulty spark plugs Trouble when cold, misfires ⭐ (replacement in 30 minutes)
2. Breakdown of ignition coils Errors P030X, trembling after rain ⭐⭐ (diagnostics required)
3. Dirty injectors Difficulties during acceleration, black carbon deposits on spark plugs ⭐⭐⭐ (cleaning or replacing)
4. Air leak into the intake manifold Floating speed, error P0171 ⭐⭐⭐⭐ (search for leaks)
5. Wear of valves or hydraulic compensators Knock on the cylinder head, tripping when hot ⭐⭐⭐⭐⭐ (cylinder head repair)

On motors HR16DE (since 2013) most often fail ignition coils — their resource rarely exceeds 80–100 thousand km. On K4M (Renault) weak point - injectors, which become clogged after 60 thousand km when refueling below AI-95.

Why does the Almera G15 check engine light often come on when tripping?

When a cylinder misfires, the unburned fuel-air mixture enters the catalyst, where it burns out. This is recorded by the lambda probe as a “rich mixture” (P0172) or "misfire" (P0300). On HR16DE The check may light up even with a brief omission, since the ECU is very sensitive to detonation.

3. Diagnosis of triplets: where to start

Before disassembling the engine, perform a simple check:

Check spark plugs for carbon deposits and gap (normal: 0.9–1.1 mm)

Inspect the high-voltage wires for breakdown (sparks are visible in the dark)

Scan for errors via ELM327 (Freeware: Torque Pro, OpenDiag)

Swap the ignition coils - if the cylinder has changed, the coil is to blame

-->

For accurate diagnosis on Almera G15 use elimination method:

  1. Turn off the injectors one by one (with the engine running). If, when one of them is turned off, the nature of the work does not change, it is clogged.
  2. Check compression. On HR16DE norm: 12–14 bar, spread between cylinders no more than 1 bar.
  3. Measure the fuel pressure (norm: 3.5–4 bar). On K4M The pressure regulator in the rail often fails.

Critical information: On Almera G15 2015–2017 exhaust there was a defect in the wiring of the ignition coils - the wires were rubbing against the intake manifold. Check the insulation of the wires near the 3rd cylinder!

4. Spark plugs: which ones to install and how to check

On Nissan Almera G15 spark plugs are installed from the factory NGK IFR6A11 (for HR16DE) or Renault 7700500168 (for K4M). The service life of original spark plugs is 30–40 thousand km, but when using gas or bad gasoline, they fail earlier.

Signs of faulty spark plugs:

  • 🔥 Oil soot - indicates oil getting into the combustion chamber (wear of rings or valve seals).
  • ⚡ Electrode erosion — an increased gap leads to misfires.
  • 💧 Wet candles — the fuel does not ignite (problem with the coil or compression).

For replacement we recommend analogues:

  • Denso IK16 - the best option for gas, resource up to 60 thousand km.
  • Bosch FR7DPX - cheaper than the original, but the quality is worse at sub-zero temperatures.
⚠️ Attention: On HR16DE Do not install spark plugs with copper electrodes (for example, NGK BPR6ES) - they burn out quickly due to the high temperature in the combustion chamber.
💡

Before replacing spark plugs, apply a little to the threads. graphite grease - this will make the next replacement easier and prevent sticking.

5. Ignition coils: how to check and which ones to choose

Ignition coils on Almera G15 - weak point. Original (Nissan 22448-JK00A) serve 60–80 thousand km, after which they begin to “break through”. Symptoms:

  • 🌧️ Trouble intensifies after rain or washing.
  • 🔌 When the coil connector is disconnected, the nature of the engine operation does not change.
  • 💥 Cracks on the case or traces of melting are visible.

Checking the coils:

  1. Measure the resistance of the primary winding (standard: 0.5–0.7 Ohm).
  2. Check the secondary winding (normal: 8–12 kOhm).
  3. Inspect the insulation for breakdown (use a tester with a continuity function).

The best analogues of the original coils:

Manufacturer Article Price (2026) Notes
Beru 0040203139 ~2500 rub. Best price/quality ratio
Denso 550018 ~3200 rub. Resource up to 100 thousand km
Bosch 0 221 504 478 ~2800 rub. Often counterfeited
💡

If tripping appears after replacing the coils, check state of contacts in ECU connectors - on Almera G15 they often oxidize.

6. Injectors and fuel system: cleaning or replacement

Clogged injectors are the second most common cause of throttling Almera G15. This is especially true for cars refueled at “dubious” gas stations. Symptoms:

  • 🛢️ Strong smell of gasoline from the exhaust pipe.
  • 📉 Increased fuel consumption (more than 9 l/100 km in the city).
  • 🔥 Black soot on candles (over-enriched mixture).

Methods for cleaning injectors:

  1. Ultrasonic cleaning (the best option, cost ~3000 rubles per set).
  2. Flushing with liquid (For example, Wynn’s or LIQUI MOLY). Effective only with light contamination.
  3. Manual cleaning (removing injectors and washing in solvent). Risk of damaging the O-rings!

If cleaning does not help, the injectors need to be replaced. Original for HR16DE: Nissan 16600-4M000 (~5000 rubles per piece). Good analogues:

  • 🔧 Denso 15640-4M000 - a complete analogue of the original.
  • 🔧 Bosch 0 280 158 502 - cheaper, but may require adaptation to the ECU.
⚠️ Attention: After replacing the injectors with Almera G15 be sure to reset the adaptations via diagnostic scanner! Otherwise, the ECU will use old calibrations, which will lead to tripping.

7. Air leaks and other “unobvious” reasons

If the spark plugs, coils and injectors are in order, but the engine still stalls, look for air leak. On Almera G15 Most often, air is sucked in through:

  • 🔗 Cracks in the corrugation of the air duct (from the air filter to the throttle).
  • 🔧 Intake manifold gasket (especially after renovation).
  • 🛠️ Canister valve (error P0441 or P0444).
  • 🔥 Vacuum brake booster (when you press the brake pedal the speed drops).

How to find the choke:

  1. Stop the engine and remove the hose from the throttle body. If there are traces of oil in it, air goes through the gasket.
  2. Use smoke generator (best way, but requires equipment).
  3. With the engine running, spray carb cleaner to potential suction sites. If the speed changes, you have found the problem.

Other rare causes of tripling Almera G15:

  • 🔋 Weak battery — when the voltage is below 11.8 V, the ECU does not control the ignition correctly.
  • 🖥️ ECU firmware failure — after disconnecting the battery or “lighting up”. Solved by flashing.
  • 🛢️ Clogged fuel filter — the pressure in the ramp drops under load (normal: 3.5–4 bar).
How to check fuel rail pressure without a pressure gauge?

Unscrew the cap on the ramp (from the injector side) and press the nipple with a screwdriver. If gasoline sprays out in a weak stream, the pressure is low (the fuel pump or pressure regulator may be to blame).

FAQ: Frequently asked questions about tripping on the Nissan Almera G15

Is it possible to drive if the engine is not working?

Short-term - yes, but no more than 100–200 km. Long-term driving with three-wheel drive leads to:

  • 🔥 Overheating of the catalyst (risk of melting).
  • 🛢️ Diluting the oil with gasoline (if the fuel in the cylinder does not burn).
  • 💥 Detonation, which destroys pistons and rings.

On HR16DE Triplication of the 4th cylinder is especially dangerous - it is closest to the catalyst.

How much does it cost to diagnose a tripe at the service?

The cost depends on the method:

  • 🔧 Computer diagnostics (ELM327 + scanner) - 500–1000 rub.
  • 🔍 Compression check — 800–1500 rub.
  • 🛠️ Full diagnostics (with analysis) — 2000–3500 rub.

On Almera G15 often offer “comprehensive diagnostics for 500 rubles.” - this is a scam. A quality check takes 1–2 hours.

What kind of oil should I fill in after repair (if the tripping was due to oil in the cylinders)?

If tripping is caused by oil getting into the combustion chamber (wear of rings, seals), after repair, use oil with:

  • 🔧 High cleaning ability (For example, Liqui Moly Top Tec 4200 5W-30).
  • 🔥 Increased heat resistance (for HR16DE critical due to high temperature).

Oil volume for HR16DE: 4.3 l (with filter replacement). After repairing the cylinder head, make the first replacement after 3000 km!

Is it possible to change the ignition coils on an Almera G15 yourself?

Yes, this is one of the simplest procedures. You will need:

  1. Disconnect the negative terminal of the battery.
  2. Remove the decorative engine cover (4 clips).
  3. Disconnect the coil connector and unscrew the fastening bolt (10mm wrench).
  4. Remove the coil by pulling it up (do not force it; if it gets sour, spray with WD-40).

Important: when installing a new coil do not touch metal parts - this may damage the electronic hardware.

What to do if tripping appears after refueling?

Most likely, the gasoline contained water or additives incompatible with HR16DE. Actions:

  1. Drain the gasoline from the tank (you can use a hose or disconnect the fuel line).
  2. Top up 100–200 ml acetone (dissolves water) or a special fuel dryer (HI-GEAR).
  3. Replace the fuel filter (part number: Nissan 16400-4M000).
  4. Drive 50-100 km at high speed (3000-4000 rpm) to burn off deposits.

If the tripping does not go away, check the spark plugs (they could have been “filled” with bad gasoline).
