Stalls while idling and engine "pops" at 4000rpm or better... im told it could be throttle position sensor, idle speed control motor, power control module, bad vacuum line, bad EGR valve, air filter, fuel filter, oxygen sensors, catalytic converter, clogged injectors, dirty carb & little green gremlins living in the engine...jesus tap dancing christ can ANYONE narrow this down for me????

Your engine has an electronic throttle body. They don't use an idle air control valve. They control idle by cracking open the throttle plate electronically. If you have idle problems, chances are you've got carbon buildup around the throttle plate. Here's how to clean it. http://ricksfreeautorepairadvice.com/clean-an-electronic-throttle-body

make sure your throttle position sensor is adjusted to correct values

I would check the IAC motor or idle air control motor, heres a little info.about the part.Stratus Sedan, 1999-2005 Idle Air Control Motor

Description & Operation

Not for Dodge Stratus Sedan
The idle air control motor (IAC) attaches to the throttle body. It is an electric stepper motor. The PCM adjusts engine idle speed through the idle air control motor to compensate for engine load, coolant temperature or barometric pressure changes. The throttle body has an air bypass passage that provides air for the engine during closed throttle idle. The idle air control motor pintle protrudes into the air bypass passage and regulates airflow through it.
The PCM adjusts engine idle speed by moving the IAC motor pintle in and out of the bypass passage. The adjustments are based on inputs the PCM receives. The inputs are from the throttle position sensor, crankshaft position sensor, coolant temperature sensor, MAP sensor, vehicle speed sensor and various switch operations (brake, park/neutral, air conditioning).

When engine rpm is above idle speed, the IAC is used for the following functions:


Off-idle dashpot Deceleration air flow control A/C compressor load control (also opens the passage slightly before the compressor is engaged so that the engine rpm does not dip down when the compressor engages)

High idle is usually caused by a vacume leak. First place to check is the cold air intake manifold. All hoses, throttle body, and sensors. Throttle Position(TPS), Mass Airflow(MAS), Idle Air Control Motor (valve) IAC. Controls Idle speed

A malfunctioning throttle system can cause both a high idle as well as an engine stall.

A dirty air intake or cracked air intake tube is often the culprit.

How to Fix an Engine High Idle in Under 15 Minutes

Shot in the dark here without knowing the vehicle but it could be an Idle Air Control valve starting to fail. An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air. An idle air control motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the idle air control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak idle air control motor. To check the idle air control motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the idle air control should move in or out. If the idle air control motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the idle air control motor is removed clean (use aerosol carburetor cleaner) the passages the idle air control uses to control idle air speed, also inspect the idle air control for a build-up on the seating (pointed) end and clean as necessary.

Idle Speed Control (ISC) Motor OPERATION Eagle Throttle Body Fuel Injection (TBI) System NOTE: The Eagle TBI system is used only on 2.5L Premier engines. The Idle Speed Control (ISC) motor is mounted to the throttle body and controlled by the PCM. The throttle lever rests against the initial adjustment screw of the actuator (plunger). The idle speed is not adjustable. The initial adjustment screw is only used to establish the initial positioning of the actuator when the ISC motor has been replaced. The actuator extends or retracts to control engine idle speed and to set throttle stop angle during deceleration. Based on inputs from the various engine control system sensors and switches to the PCM supplies current to the ISC motor to adjust the actuator position for the particular operating conditions.

check the iac (idle/air valve) it controls the idle speed during the time the engine is started or coming to a stop. iac valve is located behind the throttle body . hope this will help you with your problem!!!!

Pull AIS (automatic idle speed) or IAC (idle air control) motor off, clean with carb cleaner or throttle body spray cleaner, as well as port it came out of & see if that doesn't help or cure it. If it cures it for a while, then starts to do it again, replace it. (located on side, at front part of throttle body usually.)

possibly idle speed control valve on inlet manifold next to throttle body

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
