    checked all the basics plugs wires fluids no it wasnt raining and there are no codes. it runs fine just has a serious lack of power. all of a sudden i was thinking maf, coolant temp sensor, or o2 sensor.

    Fuel filter is PLUGGED up.
    Water in the gas.
    Kinked exhaust
    Or a plugged up cat.


    Im guessing cat. Unbolt the exhaust in front of the cat and drive it.

    flyinryanp you live in Bend Oregon? That's kinda funny cuz my dad and I had a turbo diesel 22re 4x4 with a camper and it broke down there once lol. We left it in a yard and rented a car and drove home to Canada lol :D
    Maybe it's the geography?

    i was possibly thinking clogged cat too. i live in north bend not bend different place. i would think timing but it did while driving nothing changed and it starts and idles fine. when you take off it seriously lacks power as you get to about 3000 rpms a picks up a bit. im just trying to see what commonly goes wrong with these trucks oh and just to be clear it is a 92 2wd 22re

    There are so many things that could cause this that i would bring it to a shop to have them figure out whats wrong, after they figure it out come back on here and we can walk you through how to fix it. Everything from a jumped timing chain, clogged cat, clogged fuel filter, secondary ignition break-up, blah blah blah would cause this. If i was there and could listen to your truck it would be a simple fix, but instead of having you possibly wasting your money on cats and what not how about you have a shop look at it and come back with the results....

    just my 2 cents
