    1. when driving, I take my foot off accellerator, up and down throttle no lights are on while this is on, etm or check engine

    2. When approaching a firm complete stop idle raises as if to engage the car to push me through the stop.. have to press harder to stop..???

    3. crappy mileage.. 15 city 20 hwy.. been noticing.. or worse.

    4. idle at rest after warmed up is 1000 to 1200 depending on mild fluctuations..
    Notes: I cleaned the idle control valve.. with cleaner.. after I did this the idle did a little better..

Can't believe no one mentioned this -- because it's a very old Volvo trick. Try cleaning the old one first (they get filled with carbon deposits) with carb cleaner ; until the fluid runs clear. Allow it to dry, then refit.

I have a 2001 volvo s40. It runsa smoothly most of the 99% of the time but when i come to a stop at a light or stop sign, it stalls out! I hear it could be a ( Idle air controll motor) It starts right back...

Sounds like your ETM - Electronic Throttle Module.

Search for xemodex. He has a direct replacement for 1999-2001 Volvos. I ordered mine from him, and its much better now.

Get a quote from your dealer, then compare the prices.

two things.
1 the a/c compressor is binding inside thepump(going to die)
2 if the ecm computer is doing its job, the idle air control motor on the side of the throttle body is not working properly. not nessesarily bad may need cleaned

Engine acceleration

Causes for the car accelerating on its own are:

The cable under the hood that operates the gas is getting stuck.

Throttle pedal stuck.

Idle air control valve faulty.

There is a large vacuum leak.

ECU car computer is faulty.

The most common is the IAC, the repair is not expensive, but the car cannot be driven in this conditions.

Here is the most common cause of this stall and idle speed issues, 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.
