I see nothing I hear nothing
1990 C1500 5.7 TBI
I've read some are using a heated O2 sensor when running headers. Necessary or not???
If a heated sensor is preferred which unit are you using? Where do you get power for the heater? Just find a hot, key on wire? Because I have no idea are the heated sensors 3 or 4 wires and if 4 wires where does the 4th wire go?
I'm asking because I certain my O2 sensor is contaminated when I had a head gasket leak. Of course it leaked water into the left bank and that goes right by the sensor. If I have to replace it I might as well "upgrade". 1990 C1500 5.7 TBI
Thanks!
