E38 idle tuning

[Hib Halverson]

Thanks, I'll check the plugs. I also have the ability to test for leaking injectors. Don't take lack of further info in the near term as a lack of interest. This is but one of about a dozen projects and it is not highest on my priority list.

First, run the fuel pressure test in the FSM. If the system won't hold pressure, I'd pull the injectors and have them tested by an injector service. Replace as necessary.
Pull the plugs and inspect the tips for carbon fouling.

Good luck
