I cleaned MAF sensor..easy to do.. but still rough idle
Thanks Fshfndr for the good suggestion.
I don't think it is the IAC valve. I just read that the IAC can't be cleaned.. it's not a user servicable part. It has to be replaced if bad, and the symptoms don't match mine.
The most frustrating part.. is that nothing is throwing a DTC code. I'm kind of looking back towards the idea of a vacuum leak somewhere.
Also , still wondering obut the O2 sensors? I have The Flowmaster Cat-Back American Thunder System. It hasn't presented any problems so far. I wonder if it has affected the O2 sensors because its not the stock mufflers? Then again.. its not throwing any codes? The mystyery continues...
