When in park idle runs high, also sounds loud when shifting

When the car is in park it idles high n loud. And while in drive coming to a stop, I have to step on the brakes a lil harder because for some reason its like the car don't wanna stop. Then when u release the brakes it takes off quick. Also when I shift it jerks the car a bit, and is loud. It used to happen once n awhile, but now its getting worse.

Sounds like you have a major vacuum leak someplace under the hood.Look for any hoses that are broken or came off. You should be able to hear aloud hissing noise if you have a vacuum leak,also could have a intake plenum gasket sucked in or a stuck open EGR valve.

Symptoms 2000 kia sportage Symptoms 2000 kia sportage does not do all the time. Starts runs well but driving road 50mph almost as if ignition shut off split 2nd. Stop car and while running in drive s


Some makers used Vacuum releases for their emergency brakes which had a Vacuum switch connected to the shift assembly. This would account for a stumble if Vacuum vented out through this switch.

More common for shifting stumble to occur from Park to Drive, engaging a load on the engine, not to stumble to a freewheeling Park position. Sounds like idle speed control is sluggish to stabilize the motor.

You also have idle speed control problem with A/C, kind of shows that A/C was what kept the engine running because when you turned the A/C off, the car died.

I am going to give you some Websites for wiring diagrams. Alldatadiy.com amd Autozone.com with free wiring info upon registering your vehicle.

It seems that the base Idle speed control is not working and the A/C idle speed control is.

Also check for Vacuum leaks on the intake manifold by spraying water from a pumpbottle on the seams of the gaskets.

Check ignition Relay or ignition switch for random cutouts. The fusebox layout is on the Autozone site.

I hope my solution helps.

Toyota sienna clunks when shifting to reverse


sounds like the idle is to high if it lurches, that is why you hear a clunk, you will need to find out why the idle is to high, may be a bad sensor or idle air control valve, there are no adjustment it is all computer controlled so something is wrong , i would think the check engine light would come on by now, go to an auto zone and have the computer scanned for codes.

98 ford explorer high idle


Its either a faulty idle air control valve or a faulty fuel pressure regulator.My bet would be the idle air control valve. If you pull the vacuum hose off the fuel regulator or the map sensor and fuel runs out then the regulator is bad.If you replace the control valve then you have to reset the computer.

My car slams when put into drive. is it the idle


Yes, sounds like the idle speed is too high. If you keep driving like that, you will fry the torque converter / turbine. Since idle is computer controlled, you will have to take it for service tune up. There is one possibility that the rich, high rpm idle used for cold start is not disengaging properly after the engine warms up. Air conditioning will raise the idle speed by a couple hundred rpm, so avoid using it until you have the problem fixed. BTW.....warm engine rpm in idle, and neutral should be around 700-800. Anything over 900-1100 will result in a hard shift into 1st gear and dragging at stop lights.

Growling engine noise only at idle. Cam area


Take all of the belts off for a short run at idle. If the sound goes away it is pulley related, spin each pulley and listen for bearing noise, also check for play at this time.

If the noise does not go away when the motor is driving no accessories you have a more serious problem.
