SES Light Question

Hi all,

New member here. I read earlier and performed the only "free mod" that I could find being the removal of the air silencer on my wife's '04 GT. Drove about 15-20 miles and now getting the SES light. Could it be throwing a code for the MAF sensing a different air flow? I completley removed the silencer but I'm not sure if I like the air filter being so openly exposed. Should I just trim the insert and still get the same effect? I'm new with the Mustangs as you can see what my ride is in my sig.

Glad to be aboard and hope to learn alot from everyone.

Thank you everyone. I feel like a real dumba$$, I was in a big hurry and did not have the wiring harness completley inserted. Man, am I gonna beat myself up over that one for awhile. What's your opinion on my removing the whole silencer? With the exposure the filter has now, should I be cautioned with it this way or not to worry?

But, on a positive note, just got back from the muffler shop, cut the stock mufflers out and straight piped it for her. Is a surprise, she's gonna be dumbfounded when I roll into her office parking lot to pick her up today. What a difference and it sounds pretty mean. Ahem...not as mean as my TA though!
