Car Forum / Dodge / Dodge Trucks / October 20051999 Durango Dies when I stop
It doesn't happen every time, but three times in the last six weeks. When I'm coasting to a stop at a light or about to turn a corner, the engine just quits. We replaced the coil and thought it was fixed, but it died again a few days later. Someone suggested changing the battery so we did that and the check engine light went out and stayed out (for a change) so we thought it was alright. Then it died at a light again. Other than the coil or the battery, can anyone suggest anything else it might be? The mechanic on our last visit said the fuel line is ok, but that last visit was such a hassle we can't face going back. Three times in and out and the check engine light always came back on at the first stop light. (I'm afraid to turn it over to the mechanics again.) If anyone has had this happen I'd love to hear how you fixed it. Thanks for reading and for any advice or suggestions you care to give. I never owned a Durango, but sounds like the same prob I was having with my Intrepid, turned out to be a bad O2 sensor. Your prob sounds the same, runs great but hates stop light/signs, always starts right back up tho. Dunno if it's same on the Durango, just an idea for you to check out.

There should be a ecm code stored with the check engine failure that might help narrow down the probable cause, if you or your mechanic don't have access to a obd-II scanner many auto parts stores will read the codes out for you. The O2 sensor as suggested in another post is a likely suspect if it has the original installed if you want to take another good guess at it. I've got the same year durango so I am interested in what you find, good luck.

Build-up will occur just at the point where the throttle butterflys touch the sides of the TB and it shuts off the air supply when the butterflys close. Remove the air cleaner and wash the crap out with carburetor cleaner. Sounds stupid, but the buildup becomes a real problem. I have to do it about once/year to solve the very problem that you described. So many Garys ..so.. "Clyde" >>>It doesn't happen every time, but three times in the last six weeks. >>>When I'm coasting to a stop at a light or about to turn a corner, the [quoted text clipped - 22 lines] >> >>Joe Thank you for replying. We bought the little gizmo for checking the codes to see if it was the O2 sensor, but without the check engine light on, it doesn't show any codes. We tried so hard to get rid of that darned c.e. warning and now that we need it, it's not there. Anyway, if it comes back on we'll check the codes. It's possible that all the coil changing and banging around under the hood fixed something, (silly as that sounds) because that light has never stayed gone this long. It's been five days and no check engine light yet. About that coil; We were told by a garage mechanic in Tucson (where it died the first time) that we needed a coil and he directed us to an Auto Zone there in Tucson. We bought it and put it on before heading back home. When it died the second time here at home, the Dodge dealer's mechanic said Auto Zone buys the most inexpensive parts and the coils are notorious for going bad. He sold us an "official Dodge coil". Then after it died again (this last time) my husband compared the Auto Zone's coil to the one replaced by the Dodge dealer's coil and they're exactly alike. Both made in Japan and look like clones. >Could also be built-up crap in the throttle body.

I have to do >it about once/year to solve the very problem that you described. I suggested that to my husband and he said it's fuel injected so there are no butterflies, and he recently cleaned the carburetor so that's probably not it, but he appreciates the suggestion. I don't know if he knows what he's talking about, because he's not a mechanic (not by a long shot) so..... we'll see. :) Thanks for all the replies and when we find out what's going on I'll post it here for anyone else who's having the same problem. (I think it's one of those "try this and wait and see" things.) >I suggested that to my husband and he said it's fuel injected so there >are no butterflies, and he recently cleaned the carburetor so that's [quoted text clipped - 5 lines] >post it here for anyone else who's having the same problem. (I think >it's one of those "try this and wait and see" things.) A fuel injected engine was what I was talking about. A fuel injected engiine has no carburetor. It has injectors and a throttle body (with butterflys) to control air flow to the engine. Cleaning the throttle body is a 5 minute job .. 0 expense .. and it will probly solve your problem.

My bad. I think I translated that all wrong while telling him what you said. I've re-read your advice and where you said "Remove the air cleaner and wash the crap out with carburetor cleaner" I told him that he has to clean the carburetor because the butterflies get dirty. At least that's what he said I said. He started saying "It's fuel injected" before I even finished my explanation so I thought he'd understood it. I just read him your advice and now he's happily out there cleaning the throttle body. He says that makes sense now. At first he did get a lot of black on a white t-shirt wrapped around his finger and it seems to keep coming off. He can see a lot more deeper down in there, and he hasn't even started with the carb cleaner yet. (going to run out and get some now.) He thinks it looks pretty dirty for 28 thousand miles but it's five years old and we live in the desert, so maybe that's why. Anyway, we're optimistic. :) Thank you for bothering to clear that up for me. Anyone else might have just said what an idiot and dropped it. I'll let you know if it works. >Cleaning the throttle body is a 5 minute job .. 0 expense .. and it >will probly solve your problem. Just to tie up loose ends, I think we can safely say this was our problem. It's been more than a week since we cleaned the throttle body and since then it not only hasn't died, it seems to be running better. I was cut off Friday night at an accident scene where everyone was looking for a lane to escape into, and even hitting my brakes to avoid her didn't kill the engine. I guess it's just common sense maintenance, but I had no idea we had to clean down inside the throttle body. Thanks, Clyde! You're a very smart man. :) >> I guess it's just common >sense maintenance, but I had no idea we had to clean down inside the >throttle body. Thanks, Clyde! You're a very smart man. :) Not really .. when the "fix" was recommended to me I laughed at the guy. I really did. But when I SAW it, with my own eyes, it made sense. When the butterflys close to idle position, there are just a few thousants of an inch between the edge of the butterflys and the throttle body housing. When that space clogs up with "crap" then - at idle position - the butterfly turns the air-flow completely off - and the engine dies. Glad I could help. So many Garys ..so.. "Clyde" > throttle body housing. When that space clogs up with "crap" then - at > idle position - the butterfly turns the air-flow completely off - and > the engine dies. Not exactly... that's the purpose of the idle air passage, and the idle air control motor that regulates the amount of air that flows through that passage. Now - THAT passage can, and does, clog up, and then the engine would stall, as you said. Dirty butterflies will cause a hesitation and stumbling on initial acceleration, because the PCM expects a certain amount of air to pass through with a certain TPS reading, and until the MAP sensor settles down, the PCM is going rather blind, supplying what it thinks is the correct amount of fuel, which, because of the inefficient flow of air through the crudded-up throttle body, actually results in an overly-rich condition. well this sounds like the problem that is causing my 98 durango to idle roughly and drive jerky and clicking on the check engine light. today i took it to autozone and ran a free diagnostic and got a P0307 code... #7 cylinder misfire detected...so i came home and looked it up... if this is the trick thanks you in advance Clyde. i will update if this is the FIX WIll >>>It doesn't happen every time, but three times in the last six weeks. >>>When I'm coasting to a stop at a light or about to turn a corner, the [quoted text clipped - 13 lines] >So many Garys ..so.. >"Clyde" If it's not the IAC then check this out. My 99 Durango 5.9 began to periodically die, especially in cold weather on a cold start. Would die when placed in gear. Misfire at interstate speed, would cause the converter to momentarily unlock, you could feel it and see it on the tach. No codes, no check engine light. I've got an Autotap so I compared parameters to my Dakota, no significant differences. Read in this ng that someone suggested having the computer reflashed so I took it in, cost me about $75, has ran perfect ever since (2 years ago). Might be worth a try if you can't find anything else wrong.

Yes, I have the same problem with my '96 1500 Ram, but I can tell you what it isn't. This drives me crazy. It is very intermittent. The truck was delivered with a 5.2. The crankshaft broke at 75k. I changed to a 2001 5.9 from an automatic truck. I retained the same computer, as the truck is a 5 speed, I adapted the wiring harness to the 5.9 injectors, as it is different. I retained the TB, manifold and distributor from the 5.9. I used the '96 flywheel, but I had to mill a chunk out of the back of the flywheel to balance the 5.9, as the 5.9 is externally balanced and the 5.2 is internally balanced. This is relevant because the ignition is flywheel triggered. This intermittent stalling was present with the 5.2 and it is also present with the 5.9 and I have also changed both O2 sensors and the CAT with new replacements. I have no fault codes. It is reproducable when engine is warm and lifting off the accelerator and slipping the gearbox into neutral, at the same time from a steady state cruise. If I lift my foot and keep the engine in gear, the truck drives normally. Once the fault is present, the idle speed is very low and only the use of the accelerator pedal will keep it running. The fault behaves like a bad or misadjusted idle dashpot on a carburatored engine, yet the entire throttle body manifold, exhaust and ignition systems have been changed.
