hey guys i have a 2006 rev up engine , mods stillen catback, cai ,mrev2, stage 3 clutch with 16lb flywheel. under 75% or more throttle the car like hesitates and then it takes a sec to finally kick in . it doesnt always happen but its like a 50/50 chance usually wont do it for 10 mins then the other 10 it will. i thought it might be the maf sensor so i changed that still nothing , i was thinking maybe the throttle body is bad? or could it be from bad plugs? i took it to the local autozone and they checked everythingout it wasnt throwing any codes other then the cats 02 sensors wherent there which i do have them unpluged because the hook up isnt the same on the harness . what could this be from ?

 

The only time I've ever experienced this happening on a car is when I had a cracked intake hose on one of my old POS cars. Car had the same symptoms, but threw no codes.

 

check the hoses all are good.

 

Does your car 'buck'? I had the problem and it turned out to be the camshaft AND crankshaft sensors. It gave the code for the crankshaft sensor but not camshaft sensor

 

well it didnt throw any code, but i wouldnt call it a buck its acts like the car is spinning tires and the vdc kicks in then gets back in it
