Missing when hot at idle and off idle
Car:
1992 LT1
Manual transmission
Dynaspark
Meziere e-water pump
Taylor wires
NGK TR55P plugs
87,000 miles
Issue: when the car is fully warmed up, it misfires at idle and off idle. No check engine light.
It appears to be when the fuel goes from open loop to closed loop - so I'm guessing that it's O2 sensors.
I've tried replacing the plugs - didn't go away. The wires are < 2 years old. I'm tired of throwing parts at it and can't seem to diagnose the problem accurately.
Any thoughts? Things to look for?
Thanks for the help
