preacher man Posted June 25, 2009 Share Posted June 25, 2009 I have a 1991 LS 400. By using the on board dianostic I got Code 24. All I can find out about it is that it means "check intake air temperature sensor circuit." Where is this sensor and how do I check it? The engine viabrates when I accelerate. When I first crank it, it feels very smooth. I put new spark plugs in and all wires look fine. Air filter is clean. Thanks for any guidance you can give.
