Well my check engine came on today and I been noticing a grinding noise and feel a vibration in my brake pedal when stopped. I do have the xcal2. Ans it does not have a firm shift, but not slipping.

 

Don't those Xcal tuners read codes?

Your CEL didn't come on because your feel brake issues.

 

Theres something grinding in the engine or transmission I feel it in the brake pedal when stopped and I can hear it slightly inside the cab. not so much outside. It might be because of the exhaust noise I have magnaflow exhaust. I'm going to call troyer perf today to find out if I can pull the codes.

 

Well I pulled my codes with my xcal2 and read I'm running rich. So I opened my hood and found my airforce1 intake air cleaner was off. So I put the air cleaner back on and reset the codes and drive around for about 10 miles and light is still off
