hey guys today i went to the store and came out and started my car and it soon shut back off, so i whipped out the access port and it said cylinder 1 misfire, no to explain i am running cattd stage 2 on a 07 sti with a pdx map and 17,000 on the odom. i am still useing the stock plugs, does anyone no if it might be the plugs? i was totally surprised that there was no check engine light though, this the second time it happen, the last time was about 6 months ago.

 

do you have a lightened flywheel? or crank pulley?

 

07 sti's stock tuning is crap! I had a misfire in #4 and my engine was done lol. Go have it looked at, I hope for the best!

 

yea i would have it checked out but you might try new plugs as well.

 

pull your aftermarket stuff and unmarry your ap before going to the dealer.
