this is wierd.......custom tune isnt fixing it for you guys?

Is the weird idle a PCM idle relearn? This happened to me from time to time when I had a bad battery and a bad ground connection. What was happening to me was that any time the truck was shut off the PCM would lose power and lose all learned data causing an idle relearn at every start. Since the truck ran on the alternator on the way home the PCM relearned idle enough to idle smoothly until it sat and I restarted it.

Just a thought.

ive had mine die on me too while driving... like when i pull up to a redlight. Mine also became worse when i installed my whipple. I sure hope we can find a answer to this common problem

I get that a lot also but I always tried blaming the linkage change from the stock tb to the bbk.
I guess its not that!

I think the best way is to remove the TB and clean it as you can remove the IAC and TPS better that way. But you should be able to remove the intake and IAC and spray some cleaner in the idle air path to clean it out.

i hope we can figure this out. thats the only complaint i have since installing the whipple and it bugs the crap out of me. all you other people that have this problem, what kinda tuning do you have?
