check engine light
 

My check engine light comes on and stays on for several weeks, unless I intervene, for no real reason. I took it to a dealership and they hooked it up to a computer and the thing told him that my intake manifold gasket was leaking. I talked to my usual mechanic and he said without looking at the truck that the truck could have just spit out bogus code. The weird thing is that if I disconnect the battery and then reconnect it the light stays off until I get to a stop sign and turn left downhill and then it flips on. :( All other times the truck runs fine. She runs like a top the whole time. I don't think its the gasket, it still may be, but I suspect it might be a sensor instead that is giving me a problem. I have had the F-150 96' for 5 months with no problem and I have owned a 84' of the virtually same setup since 93'. Any help on the subject would be appreciated before I go and spend 5 hundred bucks on a wild goose chase.

I think your mechanic is correct, bogus CEL. If the truck runs good and all the other gauges read good leave it alone. I have the same problem with my car, BOGUS CEL.

I finally got my on and off Check engine light fixed today. I had a cracked vacuum hose, the one from the can to the EGR. It is made of hard plastic and broke in several spots. I replaced it with a new hose and the light has not come on since.
