I erased the code and have my fingers crossed it was just an accident the computer threw that code out there...

I started the car with the A/C on (I normally keep it off when I start the car, heard it'* bad to start it with it on), then took off from my Grandparent'* house at WOT, and that'* when it came on...also, I dunno if this has anything to do with it, but I had just refueled 13 miles before it happened.

If it comes back on, I'm going to pull the plugs and check as a starting point...basically, my post is to ask if anyone thinks the WOT with the A/C on has anything to do with it? My car is sooo sluggish and hates me when I run the air, so I was thinking maybe??

Just an FYI...the car is running just as smoothly as it was before the SES light came on, no decrease in acceleration, no hesitating, nothing... :?

I am not %100 sure on this, but it may have been just a one time random thing.

Our old '02 S10 did the same thing once. I floored it, and I got a code. Took it up to AutoZone and it said Misfire, cylinder #3. We erased the code and never had another problem with it

If it comes back each time on #5, it'* either a plug or a wire.
