Most serious is the check engine light would go on for no reason.
High pitched whining from exhaust.
Dealer could not trace so it remains!
V6 economy, very surprising.
I have a 2006 V6 Mustang. The "check engine" light comes on for no reason -- Mechanics cannot tell me why. Have you discovered the solution for your problem with this issue? Raymond.
Raymond, the check engine light on Fords is just VERY sensitive, and usually means nothing. We had a '96 Mustang, and the light came on several times. Each time just tightening the gas cap or running a tank of premium through it solved the problem. We had the same problem with our 3 Explorers. The light is programmed on most cars to come on at certain intervals so you will take it to the dealer and give them $500 to turn it off. As a mechanic I've learned to just turn the light off myself and ignore it. The light on my Dodge came on at 40,000, 80,000, 120,000, 160,000, 200,000 and 240,000 miles. Each time I just turned it off and kept going. Yours may just be coming on because it is programmed to at this point. I'd just try turning it off.
Jim.
