Electrical problem
1989 Ford F150 V8 Four Wheel Drive Automatic
----------------------------------------------------------------
my check engine light comes on after about 10-15min. of driving but goes out after i shut the truck off(whether while driving or stopped). I think it may have something to do with the emmissions stuff because i have already tried giving it a full tune up including plugs,wires,cap, rotor,oil change, and filter changes to at least eliminate the possibility of being an ignition or fuel problem. If it aids any in your answer, when i start my truck up, my truck has a high idle-around 1000RPM's and seems to rev itself as if the computer thinks it may stall or can't find the TP. This high idle and revving problem has been there for more than 4 years but had no check engine light.
