SOURCE: 2004 subaru forester, 99,000 miles. Check engine

Drop in to an Autozone, or Pep Boys, or similar big parts store & they will usually scan for codes free. This will hopefully eliminate all the guess work, or at least point everyone in right direction for better diagnosis. If not obvious from codes what the problem is, get back to us and we'll help you out.

1st try and search for a vaccum leak, due to the fact that these vehicles have had some bad problems with the length of wires and hoses, if there is a vaccum leak in the vehicle somewhere that will trigger other malfunctions in your vehicle. Using a can of starting fluid or Brake cleaner spray lightly spray around our engine til you hear the motor rev-up and the spot you have sprayed will determine where your vaccum leak will be. And then check under your distributor cap for any moisture be sure to take a rag and wipe and residue off. Also check the firing order on your distributor.

I have a 2004 dodge durango and the lighting volt stable is on my dash


It has to do with the Electronic Throttle Control. ( as per the owners manual)

12. Electronic Throttle Control (ETC) Light 5.7L
Engines Only
This light informs you of a problem with the
Electronic Throttle Control system. If a problem
is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned on and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an authorized
dealer.

I have a 2004 Dodge Stratus (4cyl) that idles rough (almost stalls out), dies on start up and recently had a flashing engine light (backfire error). Any suggestions? No other issues, water pump and timing...


Could be the idle air control, once these start hanging up inside, they can cause as variety of problems with idle speed (can become wildly random) or simply a failure to idle at all.

These links should help:
Where is the idle air control valve located on 2004 Dodge Stratus

This could also be caused by a failing ignition pack.

Why does idle flucuate on 2004 Dodge Durango 4.7?


There appears to be an idle speed control problem perhaps caused by a sensor, throttle body issue, or vacuum leak around this area, in a rare occasion this could be an issue within the PCM. Although, there is no service light on there could still be stored codes on the PCM. It would be a good idea to have the computer scanned even anyway.

Stalling at low idle


I don't know this specific car. But, if it has one, check your Idle Air Valve. This can cause the engine to stall. If you can hold the gas pedal and the engine will continue to run until you let off the gas, it is likely the IAV. It will not necessarily cause the engine to run rough. That could be a number of things like spark plugs, wires or dirty injectors. It could also be a compression problem. Is the check engine light on?

Son let his car run out of gas, and when he filled it this code appeared with rough idle and stalling code 2002


I had a something similar to this happen to a girlfriend of mine. She has a 98 escort and it ran out of gas and the service engine soon light came on after she filled it up. If this is what your talking about check your owners manual. Most of the time if there is really nothing wrong with car you can drive it around ( Generally 20 min in town and 10 on the hwy with 4 idle periods (4 times of the engine being at idle) - do not cut engine off) and the light will go off. The rough idle code most likely happened when the engine ran roughly because. it was running out of gas.

Wife's durango is idling rough and running rough


With both codes pointing at TP sensor, I'd certainly take the time to replace it, as well as make sure connections to it are clean, and good. Chances are, you won't be able to take part back anyway. As far as exhaust goes, if it's leaking in the right places in may cause improper readings at sensors downstream, but if not obvious leak, I wouldn't be concentrating in that area right now.

2002 durango has recently started to stall after it has been filled up. today it would not stay running unless foot was on the gas at all times


try this.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
