I drove to a meet, the weather was cold, no rain no nothing. Car had no CEL. Turned the car on again, it was raining and it had a CEL. Car has stock intake. Won't be able to take it to dealer till tomorrow, will the car be ok? Any idea of what it may be?

 

no exhaust or test pipe? does it run normal? i think it should be fine. try resetting the ecu.

 

Check to see if your gas cap is loose.

 

Clearly you should stop driving the car to meets or in the rain.

 

How about having the CEL pulled? No point in asking what's wrong when we don't know what the car is telling you is wrong...

It's like going to a doctor and saying:

"I hurt"

the Doc asking:

"Where do you hurt?"

and you reply:

"I don't know, I just hurt."

Pretty useless to the Doc

 

You didn't happen to pump some ethanol laced fuel along the way did you? This happened to me on a cross country trip a couple of years ago. The CEL popped up and stayed on for at least two hours and of course I knew that it was the fuel. This is something we don't see in my area of the country and wasn't expeceted and only noted during the fill-up.

 

If you still have a CEL and want to save yourself some money, take the car to Autozone or a similar parts place and they should be able to pull the codes for free. Then post back what the codes are.

 

Could be a dozen things. Get the code pulled and go from there.
