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.
