SOLVED: 4.6is with "throttle briefly jammed"

[Dking078]

Throttle bodies rarely fail.

Open your DME box, remove the 3rd connector on the DME (Or just all of them) and inspect the connectors for oil/coolant residue. Yes you read that right.

It's a known issue for the M62 and can cause false positive codes related to the TB.

If you do find anything, clean it up, start the car, and HOLD the rpms for a good min at ~ 1500 (just holding it is the core here) so the car establishes control again for idle. Weird but it happens sometimes.

I will try to find some time for this next week I hope! Thanks for the advice, I remember reading about that DME box a couple times before.

I have seen the oil issue on a friend 03 540i where oil from the VANOS solenoids made it to the DME and also know about the coolant traveling to the DME connector issue as well. I installed the mechanical 88c tstat to help protect from the coolant issue.
