I just discovered this group and I have a problem I could use some help with.
I did a quick google and I see I first need to go to the parts store and see who does the free OBD check, but... In the mean time, my 1992 F-150, 5 liter has developed a slight roughness in the idle and sometimes when you put it into reverse, it will die. Otherwise it runs great. Same gas mileage, nothing else seems to have changed. About 350K miles on it ( I attribute the good running to Mobile 1 oil all it's life). Last inspection for state sticker, the tech said it passed, but the numbers were a bit high. It's had a tune up of plugs, wires and rotor, new coil. I cleaned the throttle body and that seemed to help for about a week, then it came back the same as before. Any help is appreciated!!!! I like this old truck a lot. We have been through a lot together and I intend to use it till it dies completely, which I hope won't be for a long time to come!
