I talked to someone today that said it could be something else:

-a blocked or used up Catalytic converter

- a faulty O2 sensor

- a TPS

Does that sound right? If the truck gets worse over the next few, I think I will need to bite the bullet and take it to a mechanic. If so, what diagnostic tools do they need to track this down?

Thanks (again!). This forum and the answers provided explains a bunch and is great by helping an 'old school' shade tree understand the newer technology.

Cheers.

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.

Question:

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?

Please advise.

Good old Bill

Think you should buy the COP's for a $100.00 as you put off on Oct 15, 2008, and then get back to us. We try to offer assistance, and clowns like you listen to others.

I'll take "c" for the win (c) Could this be something with a choke?
