Why is my idle so high when I stop in traffic?

2005 MPV. It was idling really rough, changed IAC, changed air filter, cleaned throttle body, cleaned mass airflow sensor. Better, but now it surges - when I approach a stop and ease off on gas it speeds up (3000RPM) and it takes a few seconds before it calms down to 1000 RPM. Any ideas?

Sometimes cleaning all that stuff can remove years of accumulated junk in small pasageways, especially around the butterfly vavle in the throttle body. This in turn allows more air into the motor than it's used to. Much like having the throttle part way open. Most newer vehicles have a learning mode. You can try unplugging your battery and letting it sit for an hour and then connect it back. This should clear the ECU memory, and the vehicle will have to go throught the learn function again. When you start the car and let it idle, DO NOT run the A/C or lights, or defroster, or anything that may put extra drain on the motor. The computer needs to establish a baseline for idle, so let it just sit and idle for a few minutes. See if that helps with the idle issue.
My wife's 06 Pathfinder started acting up after I wiped out the junk in the throttle body. It kept giving an error causing the check-engine light to come on. I would clear it and it would come back on in a day or two. After a week or so, it finally stopped coming in.

Check for any vacuum leaks from loose/disconnected/swollen hoses under the hood. Is the check engine light on? If so, scan the codes to see if any sensors may be suspect before guessing

What would cause a 2002 Tahoe to die when you let off the throttle?


1) Bad/clogged Idle Air Control (IAC) especially if you have a oil and gauss air filter.
2) Air leak in the duct between the air filter and Throttle body.
3) Bad or clogged Mass Airflow Sensor (MAF).
4) Bad Throttle Position Sensor (TPS).

Rough idle & stalling at a stop


This maybe due to a dirty Idle Air control valve or a throttle position sensor. YouTube can provide good answers for removal and testing of the Throttle Positon Sensor (TPS) as well as cleaning the Idle Air Control Valve (IAC)

2007 dodge magnum idles too high and shuts off


Check connection to the idle air control on your throttle body. The iac has a plunger that moves in & out causing idle change. If the throttle body is dirty it restricts the iac plunger travel. Tru seafoam in your gas to clean fuel injection system. Follow directions on cam! Run the complete tank to clean system. Note: you will need to change fuel filter when done.

My 93 camry start in it run i have new plugs starks plugs n cap and roller but when im driving in be at a stop light it sound like it want to cut off so i have to put it n netural in it the gas stop it...


sounds like its not getting enough of fuel. check or replace fuel filter. this will cause vehicle to die out at stops because when you come to a stop. the dirt settles to bottom of filter, and then its like it chokes out the fuel supply. Hope this helps! the reason it runs in netural, is because the engine is not under load.
