p300 code = failed inspection
Ive had the code for 8k miles. Mitsu has reflashed it per the TSB. Ive replaced the plugs also. The car has 54k on it now. All current mods Works p2, turbo back have been on the car for 35k miles with no issues. Coincidently changed the clutch and flywheel along with TRE tranny rebuild at the time the cel first occured.

Jon I did not intend to imply that the tranny is at fault. I believe it has to do with the Exedy organic clutch and the Prostreet 10.5 lb flywheel as it chatters more than stock.

Can anyone offer advice on how to pass inspection? My car cannot go longer than two days without throwing the code which doesnt allow the ecu to accumulate enough data to pass inspection. Any help would be greatly appreciated.

I wanted to update this thread as I have had my problem solved by none other than Mitsu. Turns out the primary problem was a 401 egr code. It seems that during my clutch/trans. case install my egr solenoid was damaged and I had a significant vaccum leak. Mitsu believes that this was also causing the p300 code.
The bottom line is I was able to pass inspection after driving 6 days without throwing a code.
