I will agree with you and have wanted the Dealer to change the MAF, however they are not willing to do that because it is only in the failure record and has never happen in two ignition cycles in a row. They are also wondering why the ecm is pumping so much fuel though the engine if it is at idle. The ecm should see some airflow before it pumps so much fuel that it looks as though the truck is on fire and yet won't move because the engine is running at idle. All failures have been at idle. They want me to turn the engine off the next time it happens with out clearing the fuel so as to see if it will set again and or set another code. Talking to them tomorrow again. Thanks for the info.

 

let us know how it works out

 

well they still do not want to change the MAF and I did not set any codes in the last 80 miles. Going to do some towing in the next week so it should show up then. Thanks.

 

well if you really want to set a code and cheat a little just unplug the MAF and start it up, that should do it if you just want them to change it out. just a thought haha

 

Was there any results to this problem. I know it has been a while. My truck was doing the same thing. The dealer I went to diagnosed a fuel pressure regulator as the problem. I would stumble from a stop after pulling a hill. Especially with a trailer. They said the throttle position sensor tells the FPR how much fuel to send, and it was wrong. Don't have my truck back yet the mechanic did something wrong and set off more codes and the truck was in limp mode when I picked it up.
