Get back and look at both sides. Get closer and look at each side. Push on one side--then the other.
Sma--your doing real good. Trying and not afraid to get your hands dirty. Your learning quickly and getting the hang of it. I have confidence in you.

Guys - I know it has been months but wanted to update yall. And also ask some more questions lol (should I make a new thread?)


1986 Bronco 5.0l EFI

So the backfiring has been fixed, for now, hopefully. It turned out to be the ignition throttle switch that caused a full rich scenario in the motor, which in turned caused a backfire issue on de-acceleration. Also EGR smog pulley system causing coughing while idle.

My next question for the Bronco geniuses on here is how to fix this Coolant temp sensor issue. I haven't dug too deep yet but figured I'd poke y'all with the symptoms and see what comes back.

Gauge was showing dead so I replaced sensor, it worked for maybe a day? Came back later and gauge was all the way dead again. Now I have a new sensor handy and have tried to follow the wires, do they go back to where the OBD1 reader hooks up? Anyways, any thoughts? Thanks!!
