I have an excessive idle vibration and it's running a bit rough on my '02 3.8L. In the last year or less, new plugs/wires, new MAF, new O2 sensors, 1 new injector, 1 new coil pack.

Any ideas? No SES, no codes currently.

TIA!

 

I would clean the IAC motor, clean and test the seal of the EGR valve and run some injector cleaner thru it before I got to deep into it.

 

^ Thanks -- I will try the first two and report back, I regularly use Lucas Injector Cleaner though (roughly monthly)...
