I intalled a MAC 2V GT 85mm Mass Air System (pn#3285) on my '03 GT and soon after my Check Engine Soon light came on
and I was curious if anyone had any insight on this. I have heard of this happening before on some cars. Any help would be greatly
appreciated. Thanks!

Reset your ECU.

Is this usually a on time thing or does it usually happen quite often? Thanks a million!
C!

i had the same crap happen to me on mine, same system you have....they said you were supposed to disconnect the battery for about 20 minutes before the instal then connect it when your done. what fixed mine was just doing that once installed, disconnect it for 30 minutes and just hook it back up. like the other dude said on here you need to reset it, that should work.

Make sure you put the Mass airflow sensor on the top. If not thats why you would be getting the light. I put my 85mm ProM mam on and never had a problem.
