Idle issues is it my PCM?
Idle issues is it my PCM? The LT1 acted weird in traffic stops as I was going home. All a sudden the Idle will raise up like 500rpm, nothing huge but it it would only happen when I was at a dead stop foot on the brake. It freaked me out because the car would lunge forward. It did this 3 or 4 times. Every time I would stop I would have to put the car in Nuetral so I dont rear end anyone. The Car is Stock with 130K. No Engine Codes thrown nothing. It cant be a sensor right? other wise I would of gotten a code. IS it the PCM, MAF ??? I am stumped because It doesnt do it all the time I drive it. Any help or things to look at would be great
