I was gonna change my spark plugs until I found out the plugs are $6 a piece and the parts guy told me it was probly a sensor since the ses light was coming on. He said there was a sensor other than the coolant one that measures temp. Then I remembered reading about people that changed there IAT sensor and got rid of a rough idle/ low rpm hesitation. I was having that problem and the new sensor seems to have cured it So thanks again, you guys rock!

Buy a Chilton's Manual ($30) ... it will save you from doing guesswork. When ever there is an SES light on it's usually triggered by a sensor with the ability to be checked for failures by the PCM reading it's values. Things like the Opti, Coil, Fuel Pump and Plugs can't send SES signals......
