    I have the same problem. I think it has to do w/ the map circuit. I
    wiggle the connector to the sensor and the engine runs errattic. I also
    found the o-rings on my iac motor are torn somehow.

    well to tell you the truth, if you're talking about the rough idle and the rpms go up and down and your just either sitting at the light or parked it's going to either be the purge valve or a vaccum line. i'm still working on mine, however this has been an on going problem for over a year, and it doesn't get any better with time either.

    I have same problem but now it doesn't start right away and stalls on occasion. Sometimes while driving. Found 2 mechanics who owned this vehicle that replaced Cranckshaft position sensor and corrected the problem. Going to try that. Will report back!

Hi all ,i have 03` durango & same problem,so i have some tips on how to solve idle problem,there is a valve between battery & fender.this valve has two wires & two hoses,one hose connected to air intake another to pressure valve,so if you just take the first hose off it will run good but,higher rpm & check engine lights will come on.some older models have this valve on front panel behind engine.

My 2003 Durango is idling rough and stalling when I stop at intersections. Also hesitating when cold - at start up. My mechanic suggested a transmission problem but these do not seem like the correct...


Tune up, air and fuel filters. When was the last time? Also Dodge has several software upgrades for Durango's. Both for the ECM and the TCM. You can call a dealer and ask for your truck, have the VIN number handy, they will need it.

Idles rough, rpm changing-----Goes dead at times, especially when stopping at light or stop sign.-----Also rpm changing when driving at times.


from experiance you have a faulty injector,try running a fuel cleaner through the fuel system first and see if will clear the problem if this only improves the fault then run a second lot through its cheaper than an injector.adrian,,,,,,,,,

92 Ford F150 4.9L. starts good, idles rough, dies at slow speeds


4.9 litre ?? you having a laugh its a 10ton truck engine not a pick up -global warming machine,remove the pump/sender unit and check the gauze filter also look inside tank for a something floating around ,i think the idles is not a related problem to the vehicle losing power but their is a possibility you could have a problem with the little vac operated thing on the fuel injector line that allows the fuel through only when the engine is running

Runs rough at start up,then runs okay, Hesitiates momentarily when moving from a stopped position. Occasionally wont start and runs rough, then runs okay. This problem is intermittent


you have a bad injector, if you have A... as it states on the top of the motor 2.8, 3.1 L MULTI PORT and dies or idles really rough and the exhaust smells like strong gas. most likely you have an injector that has shorted or is shorting out and from my experiences usually after a road trip or using fuel injector cleaner or buying a used car. it will cause half the motor to not run or run poorly VERY POORLY or even burn out 1 injector fuse out of 2 under hard acceleration or idles but as soon as you touch the gas pedal dies. but only if it is a MULTI PORT fuel injected motor. ive heard you want to try and replace them with bosch injectors out of a 2.9l ford bronco/ranger. only attempt if you got the mechanical know how sometimes if not done right will leak gas because of the injectors being kinda different length. research before attempting.

1998 Durango as soon as you let off the gas it dies will not idle


HI, your assessment is correct. this is a fuel filter and pump issue. i would also add a fuel injector cleaner after the replacement of the fuel pump and filter. this will scrub the fuel system and clean any debris that may exist at this point. Techtron injector cleaner is the best solution when cleaning the injector system.

I would also inspect the spark plug wires for faults as well. make sure they are fitted tightly over the plugs.
