well guys i have a problem.. i just replaced the blown motor in my GTUs with a low mileaged one. heres the problem.... the car starts and idles great.. but once you press the gas it kinda boggs down and then picks back up but after that it pops and cracks and doesnt seem to want to run for s**t!! i've already replaced the afm already so i know its not that.. i've also did the whole code reading ordeal and no codes came up what so ever. its starting to drive me insane!! ive also replaced the injectors with newer ones as well. so any ideas on this problem would be great guys. the popping and cracking starts at about 3500 rpm's. and theres also a chirping sound coming from around the clutch area. but i already have that one figured out.

 

Bump for my boi

 

timing? fuel filters?

 

thanks for the bump.. as for the timing im in the process of getting a timing light.. as for the fuel filter i have already replaced it as well. thats why im so baffled at what the problem is.. other than the timing i have no other ideas. thanks for the reply

 

what sort of low mileage motor is it???

And compression, timing, stuck aux ports, missing grounds, and cat condition are the first things I would be looking at.
