So.........started out with check engine light coming on. Truck drove fine with no issues. Got checked. P0441 code(evap emission system incorrect purge flow).When I lifted the hood I found that the hose that has the evap service port on it( two small hoses actually) were disconnected so I reconnected them, reset engine check light by taking battery cable off and putting back on, and problem solved. First time driving it after the fix and Now I have new problem. When coming to a stop or slowing down without foot on accelerator, the truck cuts off. Having to put in park, turn key to off and recrank every time. Could this have something to do with the hoses being off? As I said before the truck drive fine with no issues even with the engine light on for the short time it was until I fixed hoses. Side note when I press the gas pedal the interior dash lights get brighter and the battery gauge move just a hair. I have rechecked battery hookups since I reset engine light and all seems ok so I’m just confused at this point. Any advice at all much appreciated!

If you've only driven it once since you disconnected the battery that could be the problem. The ecu has to relearn if you do that and it can take some time for that to happen.

Ok. I did read that somewhere but wasn’t sure if it was true. It’s kinda hard to drive around so it can relearn considering it cuts off at everywhere stop or slow down below 1000 rpm but I guess I’ll keep driving it a d using neutral with gas/brake technique until it hopefully relearn sooner than later. Thanks for the info

Update.... after driving the truck around some more today I noticed it started shifting smoother and no more engine stall. I guess it did just need some time. Good to know about the ECU! Much appreciate the advice cheapskate!

All good JR. Thanks for coming back and confirming what the problem was. Way too many dead end threads on the site so nice to see someone come back once in a while.
