WONT ACCELERATE PAST 2500 RPMS - 2000 Acura TL

Year/make/model didn't post?? Would be helpful in supplying info on this problem

there can be few things...first thing first
is your car missing...if yes then check plugs, any bad wire

- check for dirty fuel injectors (have u ever cleaned fuel tank) if ok then
- if u have easy access to intank fuel pump, replace its filter..
- check for bad TPS... if ok then
- check for bad O2 sensor

A bad PTS might be the culprit...
Hope this help

Regards

IF you have a carby then take it apart and clean it out as all the throats are not working properly including the accelerator pump.

mostly the computer or the ecm but try to reset it to default maybe will work...

Have you been changing and checking engine oil frequently?

if the truck feels like,
the more gas you give it the slower it goes,
you might want to check for a converter plugging up.

you have a sticky tranny valve... they have a conditioner fluid to help w/this make sure your tranny cooler in the raideator is woorking first...

either fuel filter or fuel pump...replace filter since its cheaper. 6-12 dollars at autozone

check timing and valvs
