I bought this truck a couple of months ago. I test drove it and when I got back to the guys house it died. I assumed it was the tps same thing happened to my 01 Durango. Drove it home and it didn't stall but it was sputtering and had a check engine light for a 02 sensor. Changed the tps, iac, ignition coil, cleaned the throttle body, couldn't get the O2 sensor out but I unplugged it. Drove it to the gas station didn't sputter but it died while pulling in. Got gas went to leave it started up and died 2 seconds later. Had to keep one foot on the gas and one on the brake to get home. Let it sit for a couple days had it idling in the driveway for about 10 minutes then it stalled. Is it that O2 sensor and I should have a shop replace it. Or is there something else I need to look at. Need to figure it out fast about to remodel the bathroom and I don't think drywall is going to fit in the Durango.

 

It runs fine when you are not idling? Do you have a scan tool? Can you look at the live data and tell us what the short and long term fuel trims are at idle?

 

All I have is a cheapo scan tool that only reads and clears codes.

 

What brand IAC did you put in? Aftermarket ones have a history of not working correctly. Also what condition is the battery in? What code# did you get?

 

Got the iac from AutoZone, battery only a year old got 12.5V with no load. And got p0137 and p0138 code

 

The aftermarket IAC motors suck. They simply don't react fast enough. Ran into the same thing on the 96 I used to have. Put in a mopar unit, reset the pcm, and no more stalling.

O2 sensor codes while the sensor itself is unplugged just isn't a surprise.

 

Ok, had someone who knows more about diagnostics than me take a look. Cleared the code and disconnected the battery for a couple of minutes. The truck stalled but there was no check engine light. Put the scan tool on it anyway and got p1391. Going to have him change the crank and camshaft sensors hopefully this weekend. Will keep you guys updated. Fingers crossed.

 

Use ONLY genuine mopar sensors. The aftermarket fellers don't always play nice.

 

Don't always play nice? More like the bully who kicks your butt everyday

 

Okay took all day but I think it's fixed. Changed the crank and cam sensors, notice my cap and rotor was looking bad replaced them. Cranked up 1st try, let it idle for 20 minutes and took it for a test drive and it didn't stall. Going to do a full tune up, and take it in for a safety inspection then it's back on the road.
