I Need Tech Advice!
My car does not feel as strong as it use to and it sorta misses sometimes. Someone told me the injectors were too big but I tried my buddy's 24 lb injectors and his Mass Air. When it was cold it would miss really bad, popping back through the exhaust. Is there any was the computer in the car could be bad? Sorry to post this on here, but I need quick advice so I can start running some people.

where you at in VA?
pull all your spark plugs and look at them to make sure all your cylinders are running with the same consistancy, just look at the colors, its pretty obvious, then work from there to figure if you need more or less fuel or see if its burning oil |

Popping or a backfire through the exhaust can sometimes be caused by inadequate amounts of fuel. It sounds like you motor *might* be able to use 30lb injectors...but maybe not. Like White5.0 said, pull your plugs and look at the color(s) and go from thete.
