Default Intermittent stalling and rough idle.....

Hi all.

I wanted to put it out there to see if any others have had this issue.

For only the forth time in 6 years my van has done this.
I drive somewhere, shut it off for a bit, get back in, and start it, and it idles a little rough, not much, but noticeable. Once I put it in gear it stalls. I can start it again no problem, but once in gear, it stalls. I even drove it with the two foot method around the block to keep the rpms up, and it runs and drives but not smoothly. Once the rpms come down, it stallls.
The fix is to shut it off, as if I'm taking out the key, and then restart and its all fixed.
Cannot reproduce the problem. I have not yet checked for any codes.

Thanks.

Thanks.
I was just at my local dealership to have the ignition lock cylinder replaced as the key stuck in the start position. While there I never thought to mention this as it had not happened for ages.
I don't want to pay the 165 bucks for a checkup, if I can find a handheld reader first I will try that.

what are the specs on your van? I might be able to look it up on Identifix. No guarantees, but worth a shot.

Before i got my lovely 2014, i had an 04 which i got from an auction to see if an express van was right for me, it had the same thing going on. The gooseneck fitting that goes from the oil fill to the pass valve cover came loose, causing a vacuum leak.
You should first go to an auto parts store that has an "active scanner" and borrow it in the parking lot, record all the live readings.
Plus, get a vacuum gauge and a fuel pressure gauge.
Test all of your sensors within reach with a multimeter (cake)
