Hello, i have a 94 p/u with the ol' 22re and i am having some issues with acceleration...
When i first start the truck its all good. After 1-2 minutes of driving i am getting a bit of lag on the acceleration... However if i put the petal to the metal it seems to be fine...
It is most noticeable on the highway... Unless i have the pedal to the floor i cant seem to even do the speed limit! It seems like there is a hesitation and as soon as i push the pedal down far enough there is a lurch and i am accelerating again...
I thought it may be an ignition problem so i changed the ignition coil, plugs, and plug wires. The distributor cap looked brand new so i didnt change that. But no difference

I thought of checking the fuel filter but it appears as if i don't have one!
I recently bought the truck from a guy who had rebuilt the engine 50,000k ago maybe he didn't put a filter back in? Possibly the injectors?

I have been beating my head against a wall trying to think on what it may be... Possibly a timing issue? Or Fuel delivery... I have no idea, and im not very familiar with the engine so any help would be much appreciated!

 

yea you have a filter, its on the passenger side of the block under the intake.

is the check engine light on? sounds like a bad o2 sensor.

 

Pull the throttle body off and clean it, also check the TPS, sometimes they can go bad and develop a flat spot and cause the problem your having, if its the original TPS with a lot of miles on it, it could just be worn out. And as said above, the fuel filter is under the intake.

 

Its not throwing any codes, so i will check the tps and look for my filter. Thanks boys. I will get back to ya when i know!
