Question about 2001 Chrysler Town & Country

1 Answer

Erratic idle when in gear at a stop.

When at a stop, in drive, the engine vascilates from smooth to rough until I tap the accelerator , then when the throttle body falls back it does it again. Van runs good, starts OK, but idles rough at a prolonged stop of a few minutes. When I have the A/C on it is not as pronounced. since I don't have an rpm meter, my guess is that the rpm flux is about 50-75 rpm, but enough to make the engine labor a little.

    Where are these two items located and how can I clean them?

  • rmcatee Jan 07, 2009

    I'll try cleaning it first.

  • rmcatee Jan 09, 2009

    I pulled the idle control valve off and cleaned it very well with throttle body cleaner and put a drop of oil on the piston so it would glide easily. I put new "O" rings (2) on it and reassembled. Van idles very nicely now. Apparently when the dealer cleaned the idle control valve last time, it didn't get very clean and wasn't doing its job. Works like a champ now.

    IDLE MOTOR IS AT THROTTLE BODY AREA. EGR VALVE IS IN THE INTAKE MANIFOLD. USUALLY YOU CAN CLEAN IT WITH THROTTLE BODY CLEANER/SPRAY

I'd like to get step to step instructions on how to clean the throttle body in my 2010 Jeep Patriot


  1. Purchase "02 Sensor Safe" throttle body cleaner spray;
  2. Drive the vehicle a few miles, bringing it to full operating temperature, then park it in your driveway with the engine still running;
  3. Gain access to the throttle body, and hold your thumb on the butterfly linkage so that you can open the throttle butterfly when the engine begins to load;
  4. Begin by spraying throttle body cleaner spray on all linkages around the throttle body. If the engine begins to bog because it is aspirating throttle body cleaner, quickly open the throttle butterfly to keep the engine running.
  5. Once you have cleaned all around the throttle body, spray cleaner DIRECTLY INTO THE THROTTLE BODY, opening the throttle sufficiently to keep the engine running. It will run rough during this process but try not to let the engine stall.
  6. If the engine stalls, restart it, and continue cleaning the throttle throat until you see clean metal.
  7. Pour some fuel system cleaner into the gas tank and drive the car a little more before parking it. Try to find an excuse to accelerate hard, WIDE OPEN THROTTLE momentarily if safely possible (as when accelerating to merge into traffic on a highway).
  8. Drive back home.
  9. Done.

Rough idle smooth accleration


Check your vacuum lines and be sure your throttle body is tightened down. Carb cleaner spray can be used to find the leak. Spray it around the lines and gaskets (while the engine is running). If the idle speeds up, you found the area of the vacuum leak and the solution to your problem, possibly.

How to determine if a variable timing control solenoid is damaged from being jammed by gauze filter


Assuming there's a sensor to the control solenoid, the sensor would've sent a trouble code to the ECM, activating your "check engine" light. When you accelerate, it increases pressure in fuel lines, so if there's restriction (such as dirty fuel filter) in fuel line, then it would accelerate rough with hesitation in throttle response.

check for ghost codes, the light does not need to be on to have codes stored. I would also check your vacuum lines as these can have strange impacts on a idle. check you pcv valve to make sure it is working proper
