2003 Dodge Intrepid 2.7L Car stalls and dies when hot

I have a 2003 Dodge Intrepid. The check engine light is on but, of course no one can read it for us without paying $100 or more. We found that if you turn the key 3 times to on the code will pop up. We got a code of P0128. We have replaced the coolant temperature sensor, IAC valve, cam shaft sensor, and crank shaft sensor. If the car is cold it runs like a dream. Once the car gets warm and you slow down the idle drops and the car dies. We have a new thermostat to install but can't seem to find how to install it. It also has flickering dash lights when the headlights are turned on. The headlights don't flicker. Any help with these would great. We would really like to do it ourselves and save teh expense of taking it to the shop.

    I should mention that we almost ran it out of coolant too. Don't know if that will affect the problem. It was strange that the temperature gauge would take a long time to get warm. It never came close to overheating.

    Now I'm running into the problem of how to get the alternator out to get the the thermostat. Any ideas on how to get it out of the way?

I had a similar issue with the same car and engine. I was getting error code P0108. My coolant was low, but the problem continued after I added fluid until I bleed the system. There is a coolant bleeder at the top and front of the engine. Let the car warm up and open this slowly open and let a half a cup of coolant to escape.

    Disregard my above statement. I disconnected the ERG (Exhaust Gas Recirculation) valve and all is good for about a year! The ERG is located on the back side of the engine on the passenger side. I just disconnected the wires going to it.

2000 dodge intrepid stalls out while driving and sitting in red light why

Dodge 2000 Intrepid stalling on Traffic Light - This is caused by either wrong amount of Fuel or Air mixing in Idle condition. Please check fuel pressure at Idle which should be at least 38 psi and should go up when you press the accelerator. If fuel pressure is okay then Clean out the Throttle body carefully. This should solve the problem if no Check engine light is on. If Check engine light is on then please confirm and give me the codes present in On Board Diagnostic port (Auto Zone or Advance Auto will read the codes free for you) and we will go from there.

Warms up, check engine light comes on. then turns off car

sounds like you have a bad "Idle Air Control Valve" if it stalls while hot could also be a bad MASS AIR FLOW Sensor/MAF Sensor but it may be only sure said once you plug in an OBII Scanner so you can read that code that is causing that check engine light to come on..

Good luck.

I have a 2001 Dodge Intrepid and the engine light continues to stay on. I have taken it to a mechanic and he somehow turn the engine light off but then it popped up again. Any suggestions on what I should...

The fact that it popped up again indicates a problem. Have a mechanic or local auto parts store use their OBD-2 scanner to read the code(s). From there, they will be able to tell ou what the code(s) mean and you can choose the course of action you want to take.

It dies out when im driving,and still has power

The crankshaft sensor is a common problem for your situation. When you have a problem, it won't start as the engine is hot. Open the hood, let it cool then you can start it again. Have a shop diagnose on the crank shaft sensor and replace it. Good luck.
