Long story short my 1996 eclipse started misfiring only when driven under 2000 rpm and only when its warm outside if its cold out then it wont miss. I checked codes and got a cylinder one and four misfire, I have changed the spark plugs, wires and coil and still no luck. I am at a lost of where to check next. Any input would be greatly appreciated.

1 & 4 are the same physical coil, and the same trigger wire. Make sure the rearmost wire on the coil harness isn't frayed or grounding out, and that the back of the coil isn't cracked or the coil damaged.

Also a very common problem that happen to my 97'gs 420a, is that one of the wire's will pull out of the plug slightly, causing a bad connection, resulting in a misfire!!! Hope it helps!!!

I had replaced my coil with a known good coil and it still did the same thing. Thrn i ohm'd out my wires and 1 & 4 were out of specs so i out new ngk wires on it and still missing. I will check the plug and wires going to the coil this weekend.

I contributed to the Wiki.

Two out of the four wires were out of specs and the coil I borrowed off a buddy's car.

I meant check the plug and wires that plug into the coil not the spark plug and spark plug wires. I should have said the coil pigtail
