Can a Bad (2.0t) Evap Purge Valve Cause Misfires? | AskDap 

I had a p0455 code and never fixed it and it went away, the check engine light came back on with a p0300 code misfire code. Is this because I never fixed the purge valve code

I just replaced my purge valve which was stuck open on my Volkswagen and my misfire condition went away. It was surging when I would put the clutch in and no one could figure out why. I can start my car the first time after filling the gas tank now too.

Good video thank you. I DO wanna know who made the beat at the end? I am an audio engineer and liked what i heard.

can a clogged canister vent cause engine running diffrent not missing just stumble possibly to much fuel along with pumping gas issues

Will this part cause the cabinetry to make a knocking sound meaning the evap canister making a loud sound change it after odb reading still makingbsound

Hey can you link me to a video for replacing purge valve on CCTA engine? My right side is like a hard cable on the valve not two clamps

Hey guys, I want to share my experience. I have a '11 A3 2.0 TFSI CCZA engine (147kW). I had 2 faults on the engine: P0299 underboost, and P0441 - purge valve incorrect flow or smth. My symptoms were: cold car stinks as hell with fuel, on cold misfires when driving calm, even when hot and pushing there was this step of boost from 2500rpm and before that car was a bit slugish. Also very interesting, that on idle if I was reving pedal to the medal, the rpms were jumping from 4000 to 3700 then up again and with live diagnostics each bump down was counted as missfire. So I changed the purge valve - 06H906517AA, and guess what: car is now much smoother, power is there (the underboost fault, it was not affecting so much the performance, I did not have any check engine lights, at the Audi center they checked that there slight underboost, I think they test drove it and checked real time values), no step at 2500 it goes very smooth from zero to hero, and guess what, the idle rpms full throthle are now stable, the RPM holds at 4000 steady calm, before it was not like that. I changed only the purge valve without the plastic piping. Hope it helps for someone :) I never wanted to believe that it was carbon build up issue, as my car had new intake manifold fitted at 100k km, it had NEW original turbo fitte as well.

Hello ! I come from Brazil and my Passat 2014 TSI os getting misfire. I changed coils, spark plugs, injectors and still same misfire. Anyone can help me ? The misfire, sometimes show in cylinder 1, 3, 2. But It happens online If I push the gas pedal, quickly.

Can this cause knocking noise from the evap cannister.?ON A A8 AUDI A8 2006 4.2? ANYBODY HAD THIS ISSUE.

Like others, i'm wondering if the evap system on a whole can cause a kind of knocking sound, sometimes its rhythmic when the cars been driven quickly and its like the pressures escaping idk

Hyy can cod P0174 create code P0496? Cuz my purge valve is making tickling noises and have chk engine light. Could that valve be the solution to both codes?

hello guys , i have a toyota corolla 2015 , 1.8l , i have two codes p0441 - incorrect purge flow p2420 - evap emissions system switching valve control circuit high ( ive read that toyota calls purge solenoid the switching valve ) - ive tried to look around for broken wires or hoses or lose hoses or any other physical damage but found nothing , i think its the purge solenoid that i need to test , which is usually on the top right-ish corner of the engine if ur standing at the front of car facing the engine, one question is should i buy a multimeter to test the solenoid or can i do this pinch test like shown above in video? also for the past month or so the car has barely had any acceleration. it feels like u really need to step on the pedal to get up to some speed. it feels like the car is like suffocating , like not delivring full power i tried looking at the live data but im still pretty confused , SHFT1(%) 0.8 - 1.6 , LNFT1(%) -9.4 O2S11-- +3.3 , O2S12-- +0.115 AND THEN there was SHRTFT12(%) - 99.2 . THIS last shrtft has me scratching my head , this whole thing has me scratching my head, im so very new at this but im thinking the car is running rich cuz its getting too much fuel cuz the purge solenoid is stuck open? the oxygen sensor 11 just stayed at +3.3 didnt move or anything . im not sure what is makin it run so rough:( if anyone can guide me on what i can do , where i can start. any help would be appreciated , thankyou for taking the time to help!

2008 audi a3 2.0t fsi always misfiring cylinder 2 and 4 under load after carbon cleaning! New injectors, new plugs and coils, new HPFP, no vacuum leaks, engine compressions are good! Sad and frustrated seeing the car parked .... need help cause I don't know what else to check or do 😟

I have the same problem on my 1999 audi a4 2.8 quattro and it runs good at high rpms and at dead stop it haves rought idle I change my plugs wires and coil pack and I still have a misfire on 4 5 6 and also the purge valve is making a ticking sound

Yes on my wife's 17 mustang 2.3 it had a misfire. Ford could not diagnose it... why? Cuz check engine light did not come on yet. Went there 3x. All the had to do was look at fuel trims levels. All mechanics at stealerships are glorified parts changers. If it dont show a CEL. (Check engine light). They don't know what the hell their doing. So I borrowed my buddies snap-on scanner looked at fuel trims. Boom. Found it. Two weeks later CEL Light came on. After 20k of misfire. And 3x to ford.

Mine made my car bog out and stall... Barley driveable.

Hello Sir , i have 2012 model 1.8 litre TSI petrol Škoda Superb. After running 20 kms non stop , if I stop the vehicle for 2-3 mins and then again start then what happens is …… it starts and immediately loses power and stops. I have to crank multiple times during which it starts and stops every time……….: or else If I allow it to cool down for 15-20 mins with Bonet open then it starts and runs.
