IF you have a build up in the air hose after the air cleaner you have a problem in the air cleaner not sealing properly as air after the cleaner is supposed to be clean. As to the high revs on start check the air flow sensor connection hasn't been loosened when you removed the hose or is still working ok as if you have the problem with the accelerator it is also possible that the sensors in the line have been affected as well

SOURCE: 2001 Lexus RX starting problem. When the weather is warm the car starts easily. When it gets cooler (not even cold) you can tell it is struggling more to start. Also if you hold the key too long or

Your starter motor is on its way out is my guess.

2001 nissan pathfinder flat spot on accelerating around 3500rpm


Do you have any fault codes in the computer control modules memory? What is the fuel pressure doing when this happens? Have the fuel filter(s) ever been replaced? Are the air intake hose clamps tight?

My 2002 VW Jetta tdi , wont start.Fuel shut off solinoid OK . Has fuel at injectors. First wouldnt go past 20 mph.Timing belt apears fine. Can the ecm keep it from starting?


The first thing to check is the intake cutoff valve. It's similar to a throttle body, but is usually fully open until the engine is shut off, then it closes fully to minimize engine shudder.
Sometimes carbon will build up in the bore where it sits, and after it closes it will not reopen.
It's the first part of the intake after the plastic tube from the maf sensor/air filter housing.
You can pretty much just put your hand on it and push around a little bit, and the spring will return it to the open position. It has an arm sticking out that is actuated by a vacuum solenoid.
I thought of this because you said it would not accelerate, and carbon also builds up inside the intake manifold, reducing airflow so much that it can't get enough to accelerate.

This is assuming that you've got a situation where the engine is cranking, but not starting.

Let me know if this helps or if you have more questions. They often have problems with the glow plug circuit, but this should set a trouble code.

I have the exact same problem as the guy who could not keep car running without staying on the accelerator. So where are these air intake tubes, throttle body etc? I want to get to the idle air control...


I had the same problem about 6 months ago. I took it to get it fixed & I was told the problem was carbon build-up. They fixed it in less than 3 hours. I have no clue how to clean off the carbon build-up so I don't have any advice on that. I just figured I'd let you know that you weren't the only one to have the problem of keeping your car running without staying on the accelerator.

1999 dodge neon gas pedal won't accelerate sometimes unless you push down really hard on pedal


Try cleaning the throttle body. Use a throttle body cleaner and do not flood the throttle body with the cleaner. You will have to open the throttle up and spray around the butterfly. It most likely carbon buildup and causing the butterfly to stick when you accelerate. A couple of short sprays will be fine, clean with a cloth. You will see a lot of black buildup flow out of the throttle body. After you wipe dry, let the intake hose stay off for a few minutes for the throttle to dry out.

Accelerator pedal sticking - 2005 Pacifica


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

Was told my santa fe needs its APS replaced due to its original problem which was: I was driving the car and when I pushed on the accelerator the car did not accelerate as if it was in neutral...and it was...


'As in neutral' ? so the eingine accelerates but the car does not move? Or do you mean nothing happens? I had a problem where pushing on the accelerator and the car did not move and the engine stayed in idle. At first I thought it was the throttle cabel but the dealer could not find the problem, and of course, when I took it to the dealer the problem would not occur but as soon as I drove it off the lot it refused to accelerate across an intersection, no matter how hard I pushed on the accelerator. I solved the problem by pulling the air horn from the carb intake (fuel injection, this would be the air horn covering the throttle butterfly) with the rubber pulled from the air horn I saw a small blue screw with a sticker waring not to turn more than a quater turn at t time. I turned it one quarter turn (guessing, left or right, 50/50 chance) and the problem was solved. Apparently this is an adjustment that touches the leading edge of the butterfly keeping it from closing completely against the air intake horn and STICKING. Carbon build up will cause the buterfly flapper to stick tight and the electronic controled throttle will not break it loose no matter how hard you stomp on the accelerator. This car was not a SantaFe but you problem sounds similar. Hope this helps someone.

Accelerator pedal sticks


if it sticks when you first touch pedal clean air intake with carb cleaner. remove 3" hose from air filter and have someone press gas pedal, when you see the flap open and close that is what you need to clean. get all the black carbon out. then let sit for 30 min befor you start.
