SOURCE: wants to stall at idle.

Here is the most common cause of this stall, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: A 92 Mazda mx3 with a 1.8ltr v-6 while at an idle

change the idle air control motor and check to see if the ports are clogged, this too will cause surging idle. the idle air control motor is located on or near the throttle body

The butterfly at the air intake may be dirty. If at all possible remove the breathers leading to this and clean the butterly with carbuerator cleaner or something like it. There may be deposits and it is not breathing good.

SOURCE: my integra bogs down at higher rpms

First run a tank of a strong fuel system cleaner like BG-44K. If that doesn't help, clean the throttle body. If that doesn't help, take it to a mechanic.

2003 Lancer OZ Rally - Erratic Idle while sitting. Acceleration and normal driving is fine but when I stop for more than 10 seconds it bounces between 400 and 1000 rpms. What could be wrong?


You may be having a problem with your IACV idle air control valve. It is located on your Throttle body(follow the tube from your air cleaner to the throttle body) It will be on the the right below the tube. It is held on by three screws. It runs $430 at the dealer. I got one off of a junkyard throttle body for $30 and recycled the rest of the throttle body.

It had 85,000 miles on it. one day it bagan to idle rough but seemed fine when at higher sppeds/rpms. after a weekm I took it to the dealership and it turned out that a few of the coils/springs were shot. they also replaced my spark plugs, costing me about $550 total. But the car runs great again.
