SES Light Question

[2BudZ]

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.

The MIL shouldn't illuminate because of that.. all you did was allowed the airbox to grab a tad bit more air.. but nothing the MAF can't adjust for.

What's the code? You can have them pulled at Autozone for free. It could be your MAF came unplugged a little or something...

double check to make sure the MAF plug isnt loose, or go to autozone to get the codes pulled

Whenever the light comes on, pull the codes. You are absolutely flying blind otherwise. Reverse the change that you made and see if the code comes back again after being read and reset.

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!
