Hi, I have a 1999 Chevy Prizm and had a similar problem right after I had the engine cleaned. It turned out that the pressure washer got some water inside the spark plug boots. I limped to a mechanic who replaced the wires and plugs and it has run perfectly since. BTW, it is the best car I have ever owned. I'm at 107K now and haven't had a single problem (besides this one which wasn't it's fault. :-) I had this problem for over a year. Had the O2 sensors replaced but no help. Finally took it to the dealer. They solved the problem by changing the MAF sensor. The car runs MUCH better now too.
I have a 2001 Prism, and all i did was replace the spark plugs, and reset the battery it went away....
Apparently, turning on the air conditioning is triggering the computer to send a DTC (diagnostic trouble code) to the check engine light. It would be in your best interest to have the OBDII connector scanned and retrieve the trouble code(s) to find what is causing the check engine light to come on.
No it will not.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.

You have it checked for codes and diagnose the cause of the code.

It might be that you did not tighten the gas cap enough.
After repairing the cause of the code, you clear the code with a scan tool.
The engine coolant temp sensor can do that. If you have a check engine light on, have the codes read.
Check your gas cap. Make sure the seal is still good. This will cause the check engine light to stay on and is an easy fix.
