Low, rough idle - whats the cause?

[entscheidend 0]

PCV Valve, intake gaskets, pipe installed. (old one had oil dripping out if it)

Result - no difference in idle. still have "jerky" transmission changes for gears 1,2,3. Although it does accelerate alot quicker.

MAF Air flow meter next?

It cant be the O2 sensors - they would def. throw a code right? Actually the MAF hasnt thrown oone either.

Glenn - any ideas?

Need to check it again for you... did we drive the car with the scanner hooked up and check live data last time you called in ??
