acceleration problem

hey guys, my 2.7l standard transmission tacoma has been having problems when accelerating and going up hills. the truck jerks/bucks any time i try to accelerate or go up steep hills. this happens at around 2500rpm's or sometimes even higher. does anyone know what could be causing this problem? i feel like the rpms are high enough to not be working the transmission too hard and am worried this could be a serious transmission problem. any help would be much appreciated.

 

Maybe your drive shaft u-joints are ready to fall out.

 

I had a similar problem, it was my throttle position sensor though. Does this also occur on level ground? Do you hear any abnormal noises?

 

maybe clutch starting to slip?

 

get a code reader and watch you rfuel trims. could just be backfire/misfire/knocking.

 

Fuel filter??? Plugs and or wires??
TPS could be a good place to start looking aswell. Beings you're a manual transmission its unlikely a tranny problem. Clutch is a possibility but by your description its unlikely.

 

^^ what he said.
Changing the fuel filter sucks, took me 1.5 hours.
Also, clean the MAF too.

Post up what you find when repaired.

Good luck.

 

Check your plugs and wires. I assume you have a bad misfire under load. Similar happened to me but wouldn't happen above 3k rpm
