Hey guys i'm new here. I've spent a lot of time reasearching my issue, and replacing random parts . I have a 2000 mk4 jetta with a 2.0l 5 speed . The issue i have is very intermitin 50% of the time my car seams to run good , but the other half the time , when I'm at a stop sign / light . And take off my car hesitates big time then exspells a lot of whitish smoke . And at idle it sounds like it has a miss and the engine is shaking the car / running rough. I sometimes can smell that the car is running rich. Also has irratic idle sometimes . But like i said, it only does those things some of the times. Other times it runs great . I'm pretty sure my milage is not as good as it should be either.The check engine light is not on BTW and I've scanned it , theres 0 errors or codes
I've replaced both O2 sensors, MAF sensor, plugs and wires , coil, fuel filter ,cleaned throttle body , sea foamed it checked for vacuam leaks.
To me it seams like its a sensor starting to fail , but i'm not sure , any ideas ??
Thanks in advance
