Check engine light
Hi, I put a cold-air intake on my 1997 Bonneville SSE without a box around it and ran it for 2 weeks ,then I put a gutted stock air box on it and drove for about 50 miles and the check engine light came on . The code from AutoZone is PO113 .The PCM has determined that the input from the intake air temp sensor is higher than expected for the current operating conditions.Probable causes: 1. Check connector and wiring ( OK )2. Sensor open or shortened-replace sensor. What do you think ?

If you have two different lights then the service light I would guess is things like oil, coolant, brake fluid, stuff like that. Something like my wifes brake light in her van. It kept coming on, turned out to be low brake fluid. Added a little and haven't seen a light sense.
