    2000 4cyl automatic... just picked this up for work truck, has 100k, but
    really is lacking power, very unresponsive acceleration, and very little/no power going up hills... have changed fuel filter, plugs, wires, cleaned throttle body, fuel injectors, maf. dont ever see a check engine light, but this truck is obviously suffering from something? have looked all around the forums for answer, but most issues people have involve have the check engine light coming on, and i do not... :confused:

    Get it up to operating temperature at night then look under the truck. A clogged cat normally glows (cherry like heated metal). You also may want to try the deckplate mod to get some throttle response.

    May be on to something there. Should be a bypass plug before the cat. Pull it and give it a try, going to sound like crap for the test but may answer your question. :popcorn:

    What were you driving before?
    Have you driven any other like Tacos?

    I have almost the same truck since new (2002) and it is not fast on acceleration.
    Your talking 150 hp on a good day.

    You might try the cat test pipes on Ebay to trouble shoot the cat.
