Have you seen any black smoke or smoke in general come out of the exhaust?

First check if your FCU is hooked up properly and all the conections are soldered.

Did you change your plugs and regap them? If not try that. Use NGK brk7e plugs are try gapping them at .032

How many miles are on your car? You might need to replace your cap and rotor, I had similar problems and that worked for me.

Good Luck.

Betcha she's running too rich on the lower rpms, try to lean it out if you have a apex vafc or lower fuel press.

Could be a bad O2 sensor. Does it happen when your motor is cold?

Are you using the blue box? If it is not connected correctly, or if a wire comes off, your car will run like crap. The way to tell if it is installed correctly is check the LED, if it blinks green you are ok, if it is dark, the wiring isn't right.
