89 iroc missing trouble
i have an 89 iroc that just started cutting out after about mid throttle, changed the tps, icm, ecm, injectors, have not checked the pickup coil, one thing i did find is that it will stop missing/cutting out if the timing wire from the computer is disconneted, the one that you unhook to set the timing. and it does this with both computers that i have.

Re: 89 iroc missing trouble
turned out to be a loose connection on the main harness ground causing the miss, the timing retarding is because of the knock sensor is the wrong one.
