Hello! First time poster. Our car mechanic can’t seem to fix an issue we are having. Basically the Durango starts up just fine but within the first 60 seconds of driving it usually (not always) begins to almost putter. You hit the gas and it just doesn’t want to go, it putters more. At times (not always) the check engine light will make a dinging noise. Blink 3 times then stay on. The car has also stalled on us and sometimes it just kind of gets better and keeps driving. We are now shutting off the car at stop lights and such and that seems to stop the puttering / stalling issue (almost like we are using the car on and off as a reset)
If it doesn’t putter within the first 60 seconds it won’t do it and it’ll drive fine. So it only does this puttering when it’s “cold” annd you first get in it. Our mechanic did a tune up. Dropped the transmission pan. Replaced the thermostat. Replaced the transmission lines. Replaced the water pump. And no luck. Car continues to routinely putter and stall
Any advice? I am not a car person. Lehman terms appreciated. It’s a 2006 adventurer. Hemi. 5.7 liter. Thank you!
