Hello! The low idle code, speaking from experience, is mainly caused by a carbon fouled throttle body air valve that is not opening up at idle. Inspect throttle body for carbon build-up.and clean if necessary. WD40 the throttle shaft and linkage.

Cylinder misfire is a common cause of carbon build-up. Check each coil pack and associated wiring to determine if there is a problem.

Coming out of the rear of the air filter box is a black plastic tube called the mass air flow sensor. One end smaller than the other and a connector plug on it's side. One end connects to air filter outlet box, the other to the throttle body. Remove and clean using a Radio Shack product called DEOXIT($14.99). It is an electrical component spray. It comes with a gold contact circuit board cleaner as well; Set that to one side. Spray the membrane and reinstall. Spray the male/female connector

Start the car and see if your problem is gone...Keep me informed....I am here!


Do you have the code number. check the TPS (throttle Position Sensor) its next to the air intae. believe it or not my dad usally will use throttle cleaner in the air intake to clean it off. just a few squirts will clean it off.

2004 grand caravan 3.8L. CEL on, code P0032. Resistance across heater leads on heated sensor measured 1.2M ohms. New Bosch sensor measures 3.1 ohms. Installed it and cleared codes and drove 4 miles. Now the pending code is P0135. I read that the range for 2004 is 2.1 - 2.7 ohms. In 2005 it is 3 - 4 ohms and a firmware update is needed for 2004 that sets the acceptable range to now be 2 - 4 ohms. Recommendation was to search for a lower impedance heated sensor. Not sure if simply buying a Senso

1997 6 cylinder P0305 code keeps coming back. New plugs, wires, coil pack. Runs rough when started in morning and when backing up. Sometimes the CEL starts blinking while I'm driving.

I am at my wits end with this check engine po401 exhaust-gas recirculation and differential pressure. I have replaced the EGR valve and within a couple of miles it came back on.

I then read that the culprit could be the DPFE sensor that is part of the EGR famil

I heard a pop as I was driving and the engine light came on and subsequently started to flash. I changed the plugs and cleared the codes. Two days later, the light come on and started to flash again, and I changed the coils and cleared the codes. The next day, the light came on flashing again, and I performed a compression test, recording 150 in each cylinder, and cleared the codes again. Two days later, the same codes returned. I am now considering a timing belt job, but I need another opinion.

First before going into it that deep, what year and model? Get the codes instead of just clearing them and let me know. I can advise you on how to proceed without throwing parts at it. ... Chrysler PT Cruiser
