So my car all of a sudden stared spitting and popping only when your on it and it gets to about 4500 rpm. In 1st it doesnt happen, it does it in 2nd gear and 3 though. What could it be?
First question I have is about the CEL. Is your Check engine light on and have you checked it for codes? Ofter the computer will see something it doesn't like and respond in odd ways, but it will set a code most if the time. Use a paper clip to jump terminals E1 and TE1, turn the key on and record the number of flashes it makes, there's a chart somewhere in this section. Otherwise post back with code results.
Whenever you post up a question like this, anyone who wants to help you will need a list of mods you have done to the car, as well as recent repairs/maintainance/anything else so we can know what we're dealing with. In a nutshell, help us help you
No the light isnt on and its doesnt come on when it happens. Im running about 14lbs of boost and it does the fuel cut sometimes and the light come on when that happens. It just has intake, 3in pipe all the way, new metal head gasket, new fuel pump. I think it might be a boost leak or plugs i wasnt really sure.
