'95 LT1 breaking up at all RPMs Is it possible that a TPS can cause an LT1 to break up at all RPM's? The car doesn't do it unless it is 1) warmed up all the way and going into closed loop or 2) is really hot outside no matter how long it has sat. I changed the ICM thinking it was breaking down when it got hot, but it's running just like it was before I changed it. The car sometimes throws a code and the code is showing the left o2 running lean, and one time it showed a failure. When the SES is on, the car runs good with no missing (guessing because it's went into open loop). I'm hoping it's not the opti, but a local hot rod shop has opti's in stock at a decent price (they normally don't carry junk) but before buying an opti, I wanted to get some opinions on the TPS or is it possible that the o2 could be causing the entire thing?
