Check Engine Light
I have a 90 f-150 4.9. My check engine light comes on after about 5 or 6 miles of driving. Can turn the key off and restart and light will stay off for about 5 or 6 miles and come on again. All the guages look good and it doesn't seem to change how the engine runs.How do I check the codes to try to figure it out? Is there a link I can check out to learn how to do this?
