No Acceleration

[Pappy03]

When I give my 2000 Explorer throttle it is slow to accelerate and I can't get full throttle. I replaced the throttle sensor but it didn't help. I took it to my local auto parts store had them hook there computer to it and the is C1102. I looked it up and it came back saying acceleration sensor. Now I can't find the part anywhere. Could I maybe get some help as how to take care of the problem.

Thanks

As I understand it, that switch is only relevant to the performance (or, lack thereof) of your ABS system. Don't see how that can affect your acceleration problem. Could be a number of things...but, without knowing more about how your vehicle performs otherwise, maintenance history and, with no other codes to lend a clue, it's hard to narrow it down. Could the brakes be dragging? Partially plugged exhaust? Transmission issues? Extremely dirty fuel filter? Just a few things to consider.

Here is some discussion. c1102 rear axle ABS/ speed sensor.

First of all I want to thank everyone for all the help. I returned the throttle sensor and got another one and it helped. Now I have the code C1122 which I believe is a speed sensor but I'm not sure what it is nor can I find it. Could this affect acceleration and trying to give the car gas and the tranny downshifting.

Yep. It's in the link I posted above.

It should solve your speed sensor code...but, still don't see how it could affect acceleration and downshifting problems; although I believe those two things are probably related. Nothing I read in that thread (or others I've found) indicating a relationship between sensor and lack of power other than issues with the ABS engaging when braking at slow speeds in normal road conditions. Think there's something else going on....

I replaced my plugs, plug wires, fuel filter and throttle control sensor. When I start it up it will spit and sputter for about a minute then smooth out. When I drive it it will just bog out then smooth out until I try and give it gas and it just bogs out. Could this be a bad cat or vacuum leak? Open to suggestion. Where P0171 AND P0174 sensors located?

Those two codes do not point to a particular sensor...they are lean fuel mixture codes (both banks). Vacuum leaks are the primary cause of these...and, commonly associated with leaky intake gaskets.
