You need to do WAY WAY more describing of the car, recent maintenance, etc, or this is in no way advanced tech. My advice to you: Fluids both oil and tranny, plugs and plug wires, fuel filter and air filer if applicable ... then come back and tell us how it's running. This is the most common problem -- plug wires. Nothing beats some routine maintenance. Got any codes thrown? If so, GET THEM SCANNED. There is no way in the world we can help you if you have codes yet don't know what they are.
Good luck,

ok im up for a oil change... like 3500 miles since last one.. no recent maintance ever. next week im droping the trany to install the converter so i will change the fluid then. umm i changed plugs a couple of mo. ago but left the stock wires. i will go ahead and change fuel filter next weekend two. i havent thrown the ses light<--- is this what you are talking about when you ask if i have thrown codes.

Maybe your injectors are dirty. Try some injector cleaner. Trouble shoot with the cheap stuff first and go up from there. Hope this helps.

Is the exhaust making slight popping noises. Is your exhaust stock. Mine pops a bit due to the lack of backpressure. I like it though. sounds like an endurence race car. All I need is a nice flame coming out the rear. [img]smile.gif[/img]
