Stalling when in Drive
Hello everyone, so what I thought was fixed appears to be back....
Vehicle:2006 Commander 5.7L limited 4x4 141k miles purchased used at 139k miles (it was at a good price).
Problem: when in drive and coming to a complete stop after having been moving forward the Jeep stalls and engine dies or rpm starts to fluxuate between 550rpm (normal) to 300rpm then back to 550rpm (and it does this cycle a few times until I drive or put t in nuetral). In park the vehicle acts fine, in neutral after having driven it , it acts fine. But if I was driving and catch a red light I put it in neutral, the Jeep acts normal as soon as I put it in drive it either wants to stall or start the drop in rpm dance. If I am driving catch a red light and come to a complete stop it will stall or do the rpm dance. If I quickly step on the gas during the rpm fluctuations it will drive and not stall. This is also not an every day or every stop event.
Troubleshooting so far: I noticed a week or two ago my trans fluid was low, I added two quarts of the correct fluid (did everything per the manual, and it seemed fine up until the last few days the problem seems to be back). I changed the ignition switch and vehicle has had ignition assembly recall completed before I bought it. I also think this normally happens when the vehicle is cold or just being started after sitting for a while (motor off). Thoughts? I have researched the forums and tried what others suggested (even replaced the battery as that helped someone once before). Open to suggestions. Thanks. Let me know if I forgot to add a detail that would help you guys out in diagnosing the problem.
