Carwash and now my SERVICE ENGINE SOON light is on...
Went through the car wash yesterday and shortly after my SES light came on and my idle was rough for a few minutes. The light would stay on and then blink every few minutes...Now that I have driven it for a little while the light is just staying on and not blinking at all.
I am assuming the undercarriage wash hit some type of sensor....
Should I drive a few days and see if it turns itself off?
How do I reset the computer?
Car seems to drive perfect and idle perfect....other than the rough idle right after the wash for a few minutes...
thoughts???

2 things, go to autozone or something and see what the code is for then maybe we can give you a little more help.
and 2, for future reference, when the SES light blinks that means pull over shut it off and call for a tow. You destroying your cats and in some cases your engine when it blinks. Means engine is ignition misfiring very badly. Thus dumping fuel into exhaust (destroying cats) and depending on what else is going on, a bad misfire can damage engine (depending on how the misfire is occurring.

Car runs perfect.
I reset the ECU again...will I still be able to pull codes or do I need to wait until the light comes on again?
I am assuming my 02 sensors or my cats are bad...

having done 02 sensors on other cars, how tough are these to change on the G coupe? They seize up normally in the exhaust...my car has 97K on the odo and is in a salt/bad weather state...

They aren't that bad. Much easier once the cats are off the car, but the design of the heat shields keeps them from rusting out like other vehicles.
Did you get your fault code read? No sense in doing O2 sensors yet if you aren't sure of the code.
I've heard of water getting into intakes and causing MAF sensor issues (not common). I've also heard of people having water seep down through the rubber boot behind the battery in the engine bay. It can drip down and get the ECU wet but you might not see water inside the car (even though it could be there).
Make sure you get the fault code read and let us know what it is.
