Question about 2004 Dodge Ram 1500

1 Answer

After 15min or so, it won't hold an idle. runs fine.

I have replaced the idle control valve. it still happens. i also checked for vacuum leak. nothing there either. thinking maybe i received a bad valve? with power, it is supposed to retract. the new one didn't, just like the old one. is there a different way to check the valve?

It positions itself when key on, but that would probably be decided from all other inputs to & from computer. Only other way of testing it that I know of is with the DRB-II scan tool or another scan tools brand capable of doing same. Did you spray the port it goes into real well with throttle body cleaner as well?

What controls the opening and closing of the EGR solenoid?


ECU controls the EGR system. Check for vacuum to the valve with the engine running. There should be no vacuum. If you have vacuum disconnect the electrical to the vacuum control solenoid and see if the vacuum goes away. If it does you have a command or wiring problem and will need to trace the signal wire back to the ECU.

My 97 Dodge ram Van won't stay running.


Unless the vac leak is very large, it would not keep the engine from idling.
The computer controls idle speed by regulating how much air enters the intake thru the throttle body by use of the idle air control valve.
The throttle body could be gummed up, or the idle control valve may be faulty.

If your vehicle has one, and I think it does, check your EGR system. If the egr valve is full of carbon, it can be partially open, creating a vacuum leak. If the egr valve solenoid is bad, it could be opening the valve at the wrong time, also creating a vacuum leak. Unplug the egr vacuum hose, plug the open end of the hose and start it and see what it does. A picture of the egr is below.

Engine stalls, when stopped. Engine can be warm or cold when this happens. Could it be fuel filter or pump?


first thing to do is check for vacuum leaks. grap a can of spray carb cleaner and spray hose connections and elbows while the engine is running. the idle speed will change when you hit a leak with the spray. also clean the IAC valve. Idle air control valve. This device controls the idle speed. then clean or replace the PCV valve. The EGR valve will cause problems like this if it is clogged with deposits.

My 93 Saturn SL2 intermittent stalling issues


I would look at the egr system. First pull the valve and clean it. If you have a vacuum tester this would be a good time to test the valve itself as well. When under load you should be able to see the diaphragm engage and hold and then release as you release the vacuum. If that doesn't work check and/or replace the egr solenoid. It's located on the driver's side of the valve cover and usually runs about 60$.

Yours is a common complaint and the above is the most common remedy. Outside of that you might want to check and clean the idle air control valve and the port where it's housed. If it is extremely dirty or something managed to get stuck in there that could affect you vehicle running at idle as well.

Another thing, even though you just changed the plugs, pull one back out and look at it. If is fouled with oil you might need a new valve cover gasket which if it's leaking badly enough will impede spark.

You need to replace your idle air control valve. It is located on the throttle body with 2 screws holding it in. Should take about 15 minutes to replace and doesn't cost too much either. That will get you taken care of. Good luck. Thanks for rating my response and for using FixYa!

IDLING PROBLEMS ON 1992 ACCORD EX


Have the Idle Control Solenoid Valve cleaned up.

Or it might be defective. See steps below to check...
  1. Disconnect idle control solenoid valve electrical connector.
  2. Disconnect upper hose to solenoid valve from manifold and apply vacuum to hose. Valve should hold vacuum.
  3. Continue applying vacuum to hose and briefly energize valve by connecting battery positive terminal to the black/yellow wire terminal and negative battery terminal to the green/black wire terminal. Valve should not hold vacuum when energized.
  4. If idle control solenoid valve fails to perform as outlined, valve is defective.
