Misfiring PLEASE HELP

[JayRolla]

I started to misfire and through a cel. It was an ignition coil code. So I replaced the coil and nothing. Then the transistor and nothing. Plugs and wires are new. I swapped ECU and nothing. What else causes the car to misfire and through a ignition coil code????????

 

[just2asian]

what kind of plugs and wires are you running, also when your misfiring when is this happening? During idle? WOT?

How does the car idle? Does it die? Is it rough? How about at WOT? Any drivability issues or just the CEL?

Accell wires, NGK plugs the 6E's. The car feels like its running on two cylinders. Constant misfire, during idle, wot, anytime. Does not rev that well because of it. Does not die though idles fine with the misfire. Also before this happened, ever since ive owned the car it would start to misfire sometimes and the cel would come on. If I revved the motor up it would stop and the cel would go away, now its constant.

Sounds like a bad ECU. Have you pulled it out and inspected the caps? Also, Have you checked out your CAS? Also, are you tuning with a piggy back?

If you're misfiring like crazy with an SAFC/piggyback, check to see if your settings are correct (4 cyl, up, karman).

Readjust your CAS.

Replace/swap your ECU.

You can also try checking to see which wires you have going to which coil receiver. If one plug is switched, it can cause these symptoms.

Do you have the coils mounted in the stock brackets bolted to the engine? They must for proper electrical return path.
