2005 Pacifica Accelerator Sticks

Make sure floor mat is not compromising accelerator pedal operation. Check throttle cable for sticking and binding.... lube if necessary. Check throttle linkage at intake for sticking/binding and repair as necessary

Check that the floor mat isn't caught under the acc pedal,or the cable is fraded.take the cable off from the throttle and see if it moves freely,if not replace it.

Check the pivot point of the accelerator pedal and lubricate if possible. Check for freyed (broken) wires at the cable ends and check for kinks if you have a cable

It sounds like a leak in the sun roof seals. Better fix it right away. I had the same in my Acura and let it go. Soon I had mold and headliner damage all over the ceiling.

Spray the pedel and trottle body with fluid film because it eats away coroson and lubs at the same time.White grease also works well...Hope it helps.........

carbon buildup in the throtle body is most likely the problem you need to remove the air cleaner and buy some card cleaner. there ia a butterfly valve in the throat of the assembly that will have a carbon ring built up around it use the carb cleaner and a tooth brush to remove it this happened to my pacifica I could not believe it was something so simple I went through lubricating all the cables before I found the real problem

Have the throttle body cleaned.

go under the hood and manually move the accelerator to see what is binding it.

If you dont know how to do this then get an assistant to press on the accelerator (car does not have to be on) and whatch for the part that moves as he accelerates. Manually move this to find the binding. Please note that it is possible to have binding with in the cable assembly back to the foot pedal.

Good luck

Buy throttle body cleaner at your local parts store. Take the big intake hose off that is connected to the throttle body and air filter housing. Open up the butterfly (like you're controling the throttle at the engine). Spray this cleaner inside the throttle body, around the butterfly, where it motions back and forward on the pin. You will see a lot of carbon build up run out. Do this 2-3 times. It doesn't take a lot to clean it, just a couple of quick sprays. Wipe it clean with a clean cloth or rag. Put it all back together. It will seem hard to start for a few turn overs, but this is from the cleaner and it will dry out quick. What happens is, over time this carbon builds up where the butterfly closes and it gets (stuck) on this build up, which causes you to push harder on the gas pedal or it will not close completely. They charge will charge you like $250+ to do this and usually it's just build -up. Try it and let us know how it works for you. The cleaner $5

Take off the throttle body (very easy to do) and use carb cleaner to clean off the gunk. You have to clean both sides of the butterfly.
