engine miss at idle
Hey guys, I just bought an 87 Iroc with a rebuilt 350, and it was converted to a t-5 , the engine runs very well but I am getting a mis fire at idle and at a light cruise. where should I look to first? thanks in advance.

If the car is still running the computer checking for codes would be a good starting place. Other than that I would look at the plugs and plug wires.

As above, first check for error codes, idle car in the dark & look for shorts, check all ignition wiring, pull plugs & inspect, check timing at idle.
