i was driving today and my check engine light came on. so i checked all the fluids, everything was good.espically since i had the oil changed last week. i noticed on my driveway there is a small amount of what seems to be antifreeze but i highly doubt it could be that. i got under the car and cant see any wet spots or where the problem could be. any of you guys had this problem? any advice would be great. thx

If its anything like the S13, check the codes on the ECU.

Pull off your passenger side kick panel and unbolt your ECU, then bust out the screwdriver and run a diagnostics test.

Uhh, is it possible you overfilled the coolant and it spit a little bit out?
Any of the service guys can help you - they’re all at least somewhat knowledgeable.

Cheak engine light doesnt have anything to do with engine light unless you have way too much or none and your oil pressure sending unit sent the signal. Its prob a oxygen sensor or somthing else thats simple.

I’m not sure how good these are or not, but partsource is having a sale on Bosch O2 sensors, plugs, wires and caps. I think the o2 sensor is only going to be sold for like $35 or so with the discount. it starts… well today now May 4th (its after midnight).
