If you have a rough idle OR poor gas mileage please respond
So I have been thinking about this for a while. My truck has a rough idle and the dealer says it's 'normal'. I find this hard to believe that Ford would R&D and then produce an engine that they knew would idle poorly. I am wondering if the rough idle and poor gas mileage are dependant factors. So if you have a rough idle or poor fuel mileage or both please respond. Also please inform us of the model year of your truck, the engine, mileage, and a rating on how 'hard' you drive your truck (1-10, 10 being very hard) and any mods like intake, exhaust or tuner. My thoughts are that it is possibly an injector, air flow, or spark issue that is creating a lean or rich condition.
2007 F150 5.4 4x4 12,200miles, driving habits=5, Edge Tuner
I average about 13mpg and have a rough idle (I have tried this on all settings on the Edge including stock and it is always there)
