Which relay?
Anyone know what relay switches the O2 sensor heaters on a 96 150 W/ 4.9 MT?
I have replaced all but one and it still says all my heater circuits are intermittantly bad. No, I have no frayed wires.
I am going to try the last O2 figuring it may be causing a short and then the relay if anyone can aid me and then the PCM. I am experiencing no driveability issues but this is an annoying matter of pride.
