Durango stalling if you let off gas pedal (FIXED)
« on: April 30, 2010, 04:05:04 PM »
All right guys, my 98 durango, 5.2, runs great , no misses, power as good as ever, but, once it has warmed up it will stall if you let your foot completely off the Gas pedal, just goes right down to zero on the tach, does not studder , jerk, nothing, gas milage has not changed, you can lightly keep your foot on the pedal and it will not stall, just fluxuates up and down, eventually it will settle out and will not die, unless that is, you have the air on then it sometimes will stall no matter how long you sit and hold the pedal at 700-800 RPM, I have run fuel injector cleaner thrue it, changed the throttle postion sensor, changed the plugs, no change, code reader not any help, not showing any codes, could this just be a vaccum issue cause some times the throttle will kick in as the motor gets down to around 4-500 RPM and bring it up to a normal idle. Any suggestions would be great, thanks Larry >:(

We had  this same problem with our 2000 Durango, turned out the battery was failing and wasnt putting out the suport power needed to run all the systems. installed a fully charged new batery ( optima red top) and it never did it again.

i have removed the throttle body and cleaned it spotless,sometimes it works.as far as the battery goes,a voltmeter on a cold battery (not run for a while -like overnight) and testing the voltage should be above 12 volts.a weak battery will screw with the adaptive memory in the computer and idle quality is probably the first thing to go.last more expensive option is an internal intake/vacum leak.there is a test for it,but i dont exactly recall the procedure for it.

Customer Concern: The engine starts and stalls. No trouble codes. The engine will stay running if the accelerator pedal is held above idle. 
Tests/Procedures: 1. Clean the throttle body.

2. Run the minimum airflow test on the scan tool and verify the base idle speed is 500-600 RPM. Adjust if needed.

3. After doing the above steps, use the scan tool and perform the "Clear All Adaptives " function. 
Potential Causes: Base Idle Speed
Dirty Throttle Body

ok our 4.7 mitsushitssu powered 03 durango just started this random idle thing too as soon as you pull up to a light with the air/vent on or after like 4-5 minutes of idling with out. so its not too stupid yet. another week till I can do anything about the battery I'll go out and check the cables tomorrow morning I forgot to check after taking it in for inspection if they left any thing loose.
