Bad Idle...Still.. UGGGHHH
Well I replaced my Pre-Cat O2 as you suggested HeyYou...but my bad idle is back...it was fine for a few days. I pulled the new Pre-cat O2 and its still shiny new.
Just to re-iterate.. From cold start, truck runs fine for 1-2 mins, then starts to idle real crappy for a few minutes, then eventually settles down on its own.
Cat is new, Plenum fixed, Brand new O2 sensors pre, and post.
have taken the TB off and thoroughly cleaned it.
new plugs and wires
Brand new IAC.
Only thing I haven't replaced is the TPS...but cant really see how that would effect my idle...

problems still there without the O2 plugged in.
I had the neg battery cable unplugged the whole time I was changing the sensor, for good measure though I also turned on the headlights and cranked it to start for 10 seconds with it unplugged to make sure I got out any residual charge...so yes, I reset the PCM...
