Was just about to do some runs to see how the car was doing and checked fault codes before. Came up with:

16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-00 - -
16690 - Cylinder 6: Misfire Detected
P0306 - 35-00 - -
16686 - Cylinder 2: Misfire Detected
P0302 - 35-00 - -
16689 - Cylinder 5: Misfire Detected
P0305 - 35-00 - -

Is it ok to just clear them and do a few wot runs?
Think I just had stock plugs changed about 10K ago so I dont know whats going on.

Misfires seem to be the flavor of the week. Are you getting them at idle?

if they come back, then start worrying.

before you clear the codes, go look at block 032 (fuel trims) and tell me what they are. Irregular fuel trims can say whether or not your car is having issues, like a possible leak.

thanks. In gator al's post below did you say you lived in the SE?

ATL. ~30 min from Road Atlanta.

cylinder 4. When I took the ignition coil out and tried to take off the spark plug, I noticed it was a bit loose. So I re-torqued it and put everything back in, and no more misfires! Check the archive for misfires and you'll get a ton of other information.

Going to make sure my car is bulletproof before I start putting it through the paces.

The first real event I'm planning is a drag event on May 28th. The Import Showdown.
