    Okay a little back ground. I have a 2003 Double cab 4x2 3.4L, automatic. I just got back from a trip from Florida. I noticed a problem with only about 15 miles from the house. Okay so here is what is happening:

    When I am driving and leave off the gas and then go back to press the gas the truck does nothing for a few seconds then it picks up speed.

    Not sure if it just my truck but when i got my truck I noticed that when I am driving and let off the gas and press it again the transmission down shifts. When i say press the gas i mean just lightly press it, not floor board it.

    After reading some threads on here I think that it may be my throttle body. I hope that is the case. I sure hope that it is not the transmission.
    I haven't had the time to go out and look at it tonight since i just got back home from the trip..

    In this situation when you step back onto the gas do the engine RPMs go up immediately or is there a delay that coincides with the delayed increase in speed?

    How many miles on your truck?

    Thanks for the reply. There is a delay in the RPMs. The truck has 148000 miles on it. Last night I was trying to figure it out so i drove around the block a few times. This only happened once last night, but i put the transmission in 1st and press the gas a the truck did nothing. Like i said that only happened once. I checked the transmission fluid and it is good. Could it be the throttle positioning sensor?

    Fuel filter, EGR valve, PCV valve, throttle body - had this problem on my '93 but sold it before I could figure it out.
