Lord I ask you please don’t be my piston rings

Wrong piston rings will give white smoke not black smoke

Most often: dpf sensor fail, new sensor or rinsing dpf filter. ( Diesel particle filter)

Hello everyone, thank you very much for the video howevr it seems my issue is different, im having an issue at idle and many time i get the check engine, the issue that the engine is shaking and there is a lot of vibration on Idle, its very good when its running on the road . i change all spark plugs to irradium and coils as well even all 4 are new, as well i opned the engine air part and cleaned it and changed the 4 joins on the air area upper to the injectors, as well i changed the throttle body to a new one and still the same issue > i used liqui moly products and and changed oil always on time. rpm looks fine there is no loss in water/ oil and heating engine is good as well i cleaned many sensors that i can reach and cables using the electronic cleaners however still the same issue please help me guys, its driving me crazy... thanks ( clio 3 1,4 petrol 2007 )

The engine is dirty

Bottom line if it smells like fuel or oil or nothing you have your answer. Also after a decat expect such at startup

What about diluted/bad oil?

Very helpful video

Mine turned out to be the MAF sensor. Pumped loads of black smoke out when under load or accelerating. Job done. Thanks for the information.

No... thats detonation.

For a misfire limited to a particular cylinder (as opposed to random misfire between all cylinders): 1. Bad/worn/contaminated spark plug 2. Ignition coil failure (coil-on plug) (often a concequence of running the engine with worn spark plugs) Those two are by far the most common reasons. Much more rare: 3. Injector failure 4. Leaking/burnt valves 5. Failed valvetrain components (lifters, camshaft lobes, pushrods, valve springs, rocker arms) 6. Leaking head gaskets (actually, resulting in spark plug fouling by calcium deposits) 7. Damaged pistons, conrods or bearings 8. Manifold vacuum leaks (injector seals, although sometimes manifold gaskets too) 9. Wiring problems for injector or coil circuit (including internal PCM/control module issues) In about that order, resulted on 30 years of experience with different makes and models All other stuff mentioned here is rather a fuel mixture/fuel trim issues that might be resulting in random misfire as a consequence of too lean or too rich mixture.

Thanks for sharing such good knowledge

Thank you

Concise objective, and most importantly thorough. Thank you so much. Mi car presents these symptoms. I suspect that also intake valves are not sealing properly because the compression on each cylinder is different by a lot from one another, but it's not burning oil, and has a compression leak on the radiator and the throttle.

I just bought one 2 days ago

Everyone needs to know this one cause everybodys got one

It took much digging and experience but the ECM on 02 -06 altimas have a shared fuel pump/ ignition signal to no. 3 cylinder. After scanning much w/ my cheap scanner and throwing other parts at it I found the brain had a blown diode of all things causing that miss. Live and learn. I'll not own another unless it's earlier w/ the KDE engine.

🙄We can able to renew old ignition coil ?🤔 Easy way found the coil condition?😕

Is engine oil cause for black smoke

Blue smoke is from the engine is running rich😎

I appreciate your hard and dedication, thank u

All sound expensive

I used seafoam and still no white smoke

Toyota 5E engine it has a blck smoke

Thanks very much its helpful lesson

Thanks.

Won't even mention faulty spark plugs

Thanks for good explanation💞💞💞

great THANKS

Thanks for such amazing video
