Hi, my 2007 2.5L jetta-running rough! Please help
Codes show it's running lean. When I cold start my car the first 10 seconds run really rough, rpms drop up and down and half the time the car dies. Once it gets going though it starts running really good. We have replaced valve cover (pcv), replaced purge solenoid, replaced the MAF sensor, did a smoke test and found no leaks in the intake system and also pulled and cleaned the throttle body.
VCDS log and fault codes below. Any suggestions?
