At it again...but interesting find...
Hi all (again!).
I am still trying to get this same symptom diagnosed. Here is an update and restatement of the problem...
1) when putting the gas pedal down (close to where the kick down to the lower gear would be) the truck lurches and jerks as if missing a cylinder.
2) This issue has been minimal or very minor when the weather is cold.
3) This issue does not appear when item #2 is there and when driving very mildly.
4) As I want to tow, or use more performance out of my truck, I have to accelerate more aggressively, after a day or two, *or* when the weather warms up in the afternoon, the condition comes up again.
a) does a TPS cause this type of issue?
b) Could it be a MAF sensor? (Ford is supposed to be reliable in these)
c) Could this be something with a choke?
