okay this thing is driving me crazy and draining my pocket.starts bucking at 2300 rpm in 3rd gear continues till 3200 rpm I have replaced 02 sensor,tps,plugs,air fuel meter & have swapped out a known good maf sensor with no change.scanned the computer and no codes any one have any ideas or had a similar problem???

 

you check for an intake boot leak?

 

yeah sprayed 2+2 around intake and boot .thanks anyway

 

Fuel pump and fuel filter?

 

When you replaced your TPS did you use a voltmeter to make sure it was adjusted to spec?

When did this problem start?

 

I just purchased this truck, it had multiple problems ,the o2 sensor was flat lined and it failed emissions.replaced the o2 sensor and went through with flying colors but still had the buck. just got done replacing the fuel filter made no diff. how can you adj. the holes are not slotted

 

just replaced the fuel filter wasn't clogged, no change it runs very stong through 1st and second gear

 

They don't need to be adjusted on a 2000. I know I didn't need to adjust it on my 99. I think they needed adjustment from 95.5-97.
