2008 F-150 5.4, hesitates
hesitates when you step on the gas only when moving, from a dead stop its fine, it has done this since 12,000kms dealer can't find the problem, I've change it over to a Air Raid intake and changed the mass air flow to an after market and no change, vehicle has 78,000kms on it now and its getting worse for hesitating. I've picked up E3 plugs and will have the dealer change those for me hoping it may correct the problem.
Any suggestions ? ?
