Check your timing, spark plugs, spark plug wires. How old is the motor(year and miles). It might just be little maintenace stuff that was not taken care of if you have check all vacuum lines. Also, it could be the wiring of ECU or the ECU it self( like a bad chip). The first thing is to check the chip on the ECU(My opinion), wiring and then the rest of the stuff.

Check the rotor button for corrosion. My friend had a similar problem and this fixed it.

Tune that bitch ASAP! Most chips are generic and you will need to tune it. Otherwise look to replace your ringlands sooner than later.

Oh, what was the problem and what did you do to fix it?
