2007 Mustang Jerking and Chugging while re-accelerating
While driving at 65/70 mph and slowing down to 50/55 then slowly pressing on the gas to resume speed, the car was jerking and chugging like it wasn't getting any gas. It happened 3 times in a 30 minute period.On the same 30 minute drive back it only did it once
It doesn't do it from a dead stop only faster speeds 45mph+
Its easy to get it to duplicate while going up a hill, but can also be duplicated on flat open highway by getting up to speed and then letting off the gas a little and then pressing on it slowly.
I also noticed this issued like a year ago it would mimic the same jerking when I activated cruise control and going up a hill, but I stopped using cruise and the car was fine up until now, and this time I wasn't using cruise, its starting to do it on a regular basis.
Any Idea's on the fix or what it could be. There is no check engine light on or codes.
Parts replaced withing the year:
Plugs and Wires
-Changed Coil Pack Last night, didn't fix the issue
-Cleaned off MAF
