i have a 95 z28 with the lt1 in it it is misfiring and will barely idle i just replaced the fuel filter and that didn't do anything. does anyone know what could be wrong?

 

can anyone give me a starting point of things to check

 

check fuel pressure, check for burnt spark plug wires, check/change your spark plugs if they look bad, clean MAF (or unplug and see how it runs without it) just basic items first. If those all check out, look into either you ICM or your optispark

 

id start with the IAC in the intake

 

Is your check engine light on?

 

Whenever problems like this arise keep in mind it's either fuel related or ignition related and LT1's are notorious for having problems on both sides. Usually when a problem like this arises where the car will barely idle it's the fuel pump or a loose opti rotor.

 

it turned on for about a minute before this happened but then turned off i just ordered a cable to scan codes
