Car is 93 LS, my fiance will let it run for a few min before taking off in the mornings and leaving work (granted its cold as ***** in the morning). If he lets the car idle more than a minute or 2, his CEL comes on. Once he starts off, it goes off. It only does it when starting up or idling for a few min. when starting up..Any suggestions?

 

no one?

 

well to check wat cel its throwing you have to put the car in like a self diag mode . theres a gray plug under the pass dash stick a paper clip[ in it. then turn the key on the engine light will blink a few long blinks and few slow blinks try this and get back to me with the number of blinks

 

will do. it will be this weekend before we get a chance to

 

it could possibly the O2 heater, it may not be gettin the O2 hot enough at idle for the ECU to read but once you start moving and creating more heat from the exhaust it warms it up to op temp.
