Re: Rough idle and double code issues! Please help!
So here is my problem; our truck seems to shut off for no apparent reason when the temperature outside gets over 100 degrees. I know it sounds insane, but we just hit our "summer season" here and everytime I turn on the car anywhere between noon to 7pm it idles high, shakes a whole lot and then eventually turns itself off. We keep getting codes 335 & 336 so we changed the MAF sensor. That seemed to work for about a week. We changed out the ICM, that worked for another week. We replaced the fuel relay switch that worked for two days. We've checked for vaccum leaks, nothing. My father-in-law replaced the entire fuel system, nothing. I have no clue where to go from here. Any help would be greatly appreciated!
