Get the IAC checked.The idle air control valve.
The idle valve is probably stuck. It probably needs to be changed. This may also indicate a vacuum air leak. The idle and all other vacuum systems are connected. If one leaks, the idle may be effected.
The idle air control motor (IAC) is located at the top/front of the throttle housing and has a black electrical connector with four wires attached to it. The nose of the "new" IAC valve must not exceed 28mm or upon installation the "new" IAC can be damaged according to the installation instructions in the workshop manual.  Simply remove the screws securing it to the throttle housing and replace. 

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Either there is a vacuum leak which is most common, or you could have a dirty IAC valve. Check for any vacuum leaks first.

    Vaccum leak is a leak in one of the rubber black vacuum lines.
    Everything needs to be at a certain vacuum pressure or it can throw the entire engine off.

    A dirty throttle body can do this also. Same with a faulty camshaft position sensor.

My 1998 200sx stopped accelerating while getting on freeway.


Could be the cable that actavates the throttle plate on the intake..
The cable comes from the gas pedel and pulls on the throttle plane in the intake manifold.. opening the plate to let air flow through to the engine. On the other side from the cable is a plastic sensor with wires attached to it this is the Throttle position sensor.. if this is disconnected or broken the computer cannot receive the single that you are pushing on the gas pedel.. very rare for the throttle position sensor to break completly.. best posibility broken cable.. open hood find cable connected to throttle body, have someone in car push pedel see if it moves. Good luck.

2004 chevy malibu high rpms and revving all by itself


Have the engine checked for vacuum leaks, that will cause a high idle speed. As a 35 year veteran of auto repair I can tell you that engine flushs are a 100% waste of your hard earned money.

2005 dodge neon - revs high in park nuetral and tough to push break pedal down. mechanic doesn't know what it is. Anyone have this problem resolved before? Thanks


sounds to me like you have a vacuum leak. When you lose vacuum the brake booster doesn't operate right. You need to go too a different mechanic. Could be the idle selonoid staying open or even a bad brake booster or vacuum hose came off.

I have a 2002 durango 4.7. I have a hard time starting it hot or cold.when i get it started it idles fine for a few minuts and then rpm drop and wants to stall out,The truck runs great wile driving but...


First off, how new is your battery and how many miles on the D? Dodge vehicles are very sensitive to a failing battery. Have it load tested, and if is the least bit flaky, replace it.

After that, the TPS or throttle postion sensor is your next.

As far as the revving up and down above 3000 rpm goes, that is the PCM protecting the engine from over revving.

My stop lights wont go off. Stay on all the tima.


There is a button above your brake pedel that probably isn't being pushed in all the way by the brake pedel to shut them off. Try pulling up on the brake pedel and have someone watch to see if they go off when you do that. If so the button for the brake pedel needs to be adjusted so it shut them off when the pedel is not pushed.
