Falcon Fixer

2011 GT, 4400 miles on the clock.
Just got a CEL this afternoon.
Steeda intake and tune.
It is cold, 30f.
Could the cold "Help" to cause a CEL?
My last car (2006Cobalt SS/SC) was prone to throwing a CEL with a CAI and cold outside air.

I have NOT seen this issue on the Mustangs boards that I am on, so maybe my car really does have a problem.
Made an appointment for thursday.

NO, a bad tune will help with a CEL, or there is an air leak somewhere. Your hand held device will pull codes to help narrow down the problem.

How long have you been driving around before the light came on. Did it happen right after you put it on?

Also, did you scan the code with your tuner to see what the code actually is?

3000 miles since install.
P0300 code, Misfire.
Hose clamp for the air filter worked lose.
Tightened clamp, LIGHTS OUT.

Thanx guys.

I got the same error code from the Brenspeed race tune and Steeda Intake. I checked all of the hoses and seals were all tight. I installed the street tune and the light went away. Happened after about 1000 after install.
