Heres the deal, I got my car back from my local speed shop in Nov. Runs great when hot but idles like crap when cold, it stumbles, bucks all the good stuff. I was supposed to take it back to them after the motor broke in but whadda ya know there out of business. Car has 2 codes, code 26 MAF flow out of range, and i believe its code 15 for some ECM code which i assume is from the custom chip in it. The car is going to Anderson Ford Motorsport on April 6 getting the PMS system and there going to do the tune i am tired of messing around with crappy shops. I am trying to get the car running as good as possible to cut down on labor costs. This is what i have done so far.
1. Unplugged Mass Air Meter car idles great.
2. changed sensor out with 3 different sensors same result
3. checked for voltage between wires A and B on the connector - it has 11.8 volts
4. check for ohms between MAF SIG and Ground number is above minimum
I have no idea what to do next but i am sure the MAF is the cause of the idle problems because when i unplug it , shes idles great.
