Please help diagnose my LT1!! Ok so my car has been going through some issues latily, I have replaced the MAF senson, TPS, MAP and the 4L60e tranny.
Everything is good, and its shifting great, my car's normal temp is 180-200, but once it gets to 210.. it starts doing some strange things. It will develop a small miss to it, will idle up higher, sputters while in the throttle but over about 2500 rpms it clears up and runs great, but shakes a bit up to there..
let me say that it is only when it is around 205-210, does not do it below up to 180! i do not understand, maybe a burnt plug wire, maybe a bad plug, maybe a fuel filter? hell idk. when it first cranks it cranks right up and runs awesome and sounds great but once it gets to the certain temp it starts acting up..
what's your diagnois on this??

If the problem goes away either the module or coil is heat sensitive. If no change you wasted pocket change and 20 minutes.
Good luck
