IIRC, your car is OBDII, check with a local Autozone store, or someplace that has a scanner to pul the code from the car's computer. This will help in narrowing down some possible causes.

In my '92, whenever the CEL turns on, the Trac Off light turns on as well. The traction control was made to turn off if there's a CEL, so I think there's no problem with your TCS. Unless they changed it for the 2nd gen, you most likely only have a code(s?) for the engine.

You've got OBDII, so as stated, you'll need to get it scanned.

Thank you guys. I have my car scanned at Autozone, the clerk said it is the spark plugs.
I check the air filter and found it was really dirty. I thank the engine light was caused by the dirty filter and humidity. I replaced it and disconeted the battery and reconeted it. The lights went off and never come on in a couple days. But I thank it is time to replace spark plugs and wire set. I have got them and do it this saturday.

what code did he pull?
i'm always suspicious when a clerk working at a PARTS store tells me my car needs some new PARTS instead of telling me the code he pulled and rationale behind the recco..

Since when does the computer throw a code for spark plugs.
