so had the h/c/i running good and idleing good for a day. went out an raced a few guys. and after the last race the car would not idle. and still wont. you start it up and it dies with no struggle at all. feels like you turn the car off. any ideas
tune, yes, but if it idled ok before, then there may be something else going on too. did you try resetting the computer by disconnecting the battery? that could tell you if the computer "adapted" and not it doesn't like things, or not.
might the last race have caused a vacuum tube to come off or something?
Check all the connections. Do a cylinder balance test. If it still wont idle, raise the idle speed to 1k. That did it for me in the interim stage after h/c/i but before the tweecer was up and running.
