Service Engine Light
Truck has a V 6 engine, after driving for 20 or so miles the service engine light comes on. When I turn the engine off and start it again the light does not come on until it has been driven for awhile. Stopped at one shop and told the tech about it. He said as long as it goes off don't worry about it, it is only minor.
1992 Vintage 1500 O2 senor(s) Most likely. Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. Write them down.How many miles on it?
