I have changed all sensors showing problems. Origionally had very weak spark I changed distributor and have blue spark. Plugs are fouling with rich mixture and engine misfires. Do you think I have pcm problem. Even after sensors have been changed they show codes. when checked they show ok.
Has anyone experienced wiring problems such as harness on these vehicles. All plug wires , plugs , rotor. codes were given on intake temperature sensor, coolant temp sensor, throttle position sensor, and battery temp
