LT1 problems

Okay so i got it running again, but i have some ?s. First the icm i had was for a 94 I didn't know if that would make a difference since my car is speed density an 94s are mass airflow? It ran like **** with the 94 one but i put my old one an it started up fine does. It still doesn't seem wright an it broke up a little bit in higher rpms, this is leading me to believe its the ICM what do some of you other guys on here think

I would say have both the ICM and coil tested. Also, how old are the plugs and wires? Test you fuel pressure under load while you are at it.

I guess try to find another ICM to swap in and drive it. But missing on the top end sounds like the opti if it's no the coil, plugs, wires, or fuel pressure.

What way you use it?

Should I make a right turn?
Is this the right way to turn?
