i have a 94 z28 with nothing but a cold air intake. at the top of each gear it starts to pop real bad. we thought it was the fuel pump so we changed it, still doing it. i heard it could be my plug wires but i don't have to let off the throttle for it to shift and it feels fine when i drive it normal. some people say tranny going out. others say its running lien.what do you think. i'd like to know, it's driving me crazy.

 

One day I was beating on my car and reved it too high I think.. right after than the belt started squeeking and has been ever since. Along with the belt, whenever I ream on it, at about 5k or above the car just spits and pops real bad. In addition to the belt sqeek I have new plugs but I have a feeling they aren't very good. I know I have a coroded coil wire and my plugs kept falling out from a ****ty mechanic. I don't know what it could be but after my high rev causing the belt sqeek is when the full throttle high rpm pop sounds began. But I know my plugs or wires aren't very good either..

 

hitting the rev limiter??

 

Valve springs?

 

Maybe it is kicking your *** for not sending me the hood and headlight I payed for from you. SO pretty much stealing my money. THis guy is a theif and nobody worth trying to talk to or help out on here. He ripped me off for $240 dollars.
