Rough idle, check engine light then goes away

[Dominic123]

I have a 2010 panamera turbo with 56k miles with a tuned file with 622 hp; use as my daily driver; been running great and no issues; then today after leaving appt I start and starts idling very rough; no lights come on; I was low on fuel yet no indicator light; drove to station fine and filled up.

Ran some more errands and no issues; then leave last one and as I'm driving stop and go engine comes on, psm light and start/stop disengage light all appear; engine running very rough.

Pull over and turn off and restart; roughness goes away after couple minutes and I drive back to office with all the lights still on; leave office later and all lights are off and runs fine.

Any ideas would be appreciated

You need to get the car scanned with a Porsche specific scan tool (Durametric, PIWIS) to find out what codes it is throwing; without that anything would be a guess and not the basis for action steps.

Well they jjust performed the 60k service, changed all the spark plugs which were original; it did same thing again then check engine went off and runs fine.

They said next would be to replace coil wires, yet they inspected all and no cracks; maybe a clogged injector; going to run a couple tanks with techron and see if that helps.
