Just an update on my car if anyone's interested... I took my car to the dealer Monday after I returned it to "stock", and they found a faulty #3 injector and replaced it under my 60 day used car warranty
The car runs much better now and I havent had a single code or misfire since, and I even installed my new Cobb S1 aggressive 93 map... and man oh man does it run GREAT! Now its time to re-install the rest of my mods
