  1. 5.0L Tech
    I have a problem where after about 8-10 minutes of driving, the car starts bucking and jerking under any type of driving, idle starts to be low and surge and the car sometime backfires at idle. In the morning while I drive when the engine is cold, it drives like normal. Things I have replaced...

    About two weeks ago I noticed a slight hesitation when in 5th gear around 45mph. It only happens when cruising and goes away with any acceleration. In order for it to do it you have to be just slightly touching the petal. I mean slightly touching it. Just to keep the same speed going. No check...

    My 2007 v6 Mustang has been having problems. The wrench light comes on and it starts hesitating/bucking intermittently and loses power. I can't seem to drive it as fast. It started doing this around November when it started getting cold and wet outside. It eventually just went away. In...

    Hello, I have had a problem with my Mustang for quite a while now. The thing is, at low rpms, before 2k to be specific, it misfires. Its as if the timing is not correct. There is also the lack of power. The car also jerks back and forth, the engine sounds as if its spluttering. Another problem...
