I have a 95 Talon with the same motor but manual. My car was doing the same thing and I narrowed it down to the ECU cutting power to the ASD. So basically it was being told to do this. The only things that I know that cause this is the CAS, CPS. Get a multimeter and test the middle prong of the coil connector with key to ON. Should be 12v. When it stalls does it not start up for a few minutes? When it wont immediately restart check the coil power again and if 0 with key to ON then your ECU is cutting off or ASD is going bad. Either ADS or the problem was your crankshaft position sensor is bad most likely. Will appear as though ECu is going out.

2002 gmc envoy stalls when turning and slowing down


I am going to assume the check engine light is not on.
I would check the throttle body to see if it needs to be cleaned, and check the idle air control valve to see if it is working. The computer controls idle speed by the amount of air coming into the throttle body.
The ac problem is probably something different such as low freon or a cooling fan problem.

Want to verify reasons why 95 Honda Odyssee engine wants to stall and die at low speed


This is almost always caused by a dirty throttle valve and automatic idle speed control valve which is on the throttle body. Do the following to clean the system up.

To correct this problem Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional.

Dies when gas pedal is pressed


This engine has automatic idle speed control, the computer controls a "air bypass" valve on the side of the throttle body where the air intake hose from the air cleaner is connected, the valve and the throttle butterfly get "sludged" up and this causes all kinds of idle problems and off idle stall, see full list below and fix for the problems

Here is the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.

CAR RUNS GREAT, STARTED DIEING WHEN A/C WAS TURNED ON, NOW A FEW DAYS LATER IT DIES EVEN WITHOUT A/C ON, RUNS BUT WILL NOT IDLE


CHECK IDLE SPEED SHOULD BE 650 - 850 RPM. IF IDLE TOO LOW AC WILL PUT DRAG SLOW DOWN ENGINE CAUSING ENGINE TO STALL IF IDLE SPEED IS TOO LOW.

2001 volvo s80 rough ideal below 40 mph especially when the ac is on. Also if i press the throttle while in park or in drive at low speed the ideal gets rough (pulsates and often stalls).


SOUND IDLE AIR CONTROL VALVE NOT WORKING PROPERLY.IT SHOULD STEP UP IDLING WHEN YOU TURN ON THE AC TO KEEP ENGINE FROM STALLING OUT.

Dies when i stop


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, 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

Jeep stalls



I had the same problem... frustrating.

I picked up a repair manual at the parts store. I took off the throttle body and cleaned it with throttle body cleaner spray. I changed the Idle Air Control Valve (idle speed motor) which was very clogged. While I had the throttle body off I also changed the Map Sensor and Throttle Position Sensor. The manual will walk you through the steps. I had never done anything like this before. If I can do you so can you.
My Jeep has never run better. Good Luck
