im convinced my car is playing games with me, since having my car tuned with a pulley drop, my car has been driving fine normally, shifts normally under all vacuum pressure, except when i boost, cold start (yes i know its bad to beat on a car when its cold) if i boost ( currently making 10lbs) full throttle it downshifts fine and accelerates fast, id say once it reaches about 160* if i hit it, it downshifts but the rpms hesitate for a few seconds and jump and then it finally accelerates fine and makes full boost, it almost makes a purring sound. its very intermittent though, sometimes if im doing 60 and i do a pass to 85 itll shift down no problem no hesitation nothing, other itll almost bog down with the purring sound. i thought it was a trans problem, except every now and then i get an SES flashing light, sometimes cyl 4 sometimes cyl 6, i checked all plugs, wires, and swapped coil packs and it doesnt change the problem.
SOMEONE PLEASE HELP!![]()
