Igntion coil identification

[Yamahaulin]

My 2 inner cylinders don't appear to be running as good as the outer 2 based on spark plugs. I think it may be a weak coil, how do i tell what coil pack i have on my car. The car is a 95 but has a 90 model 6 bolt motor. I check extreme psi out and they offer 3 differenet coils, and 2 of them will work on the 90, so what is the tell tell so that i know what coil i'm using.

Which ECU are you running (1g/which year or 2g/which year)? the engine itself doesn't determine the spark order, the computer does. get the ignition coil for the year of your ECU.

Well i know it's a 2g ecu, I'm not sure on the year maybe it's a 95 same as the car. Anyway to tell?

Im not 100% sure... I'm going ot be ripping out my glove box today, I'll take a look and see if there's anything on my ECU that identifies it as a 95.

according to the chiltons, all 4g63 have an ignition coil firing order of 1 - 3 - 4 - 2

Mine works i just think it's not putting out same power to inner 2 cylinders as they don't look as good as the outer two. I'm gonna get a new one and there are 3 of them and 2 different prices. I will take it off and take some pics and that might help you guys help me determine what year i need.
