Check Engine Light & Warning light on

Chomper · 11-23-2006, 12:11 AM

I don't know why my check engine light and warning light (on top of speedometer) are on. I have a 93 na supra. The first time they came on for about 10 secs then turned back off. The next day after, it turned on continously. Today I thought I felt the engine idling wierd at a stop. Can anyone please help me out with this?

Almost sounds like an O2 sensor on it's way out ,but before you run off and buy one you should get the diagnostic codes from the car to be sure.

You should be able to check the code using this procedure:
