Took it a trusted, yet mainstream (as in, their people having been going to our Church forever and prefer American as opposed to German mindset), put it up on the rack.

They explained my high-idle (2000 rpm on most days) as someone having previously set it high to compensate (read, over-compensate) for a too-rich fuel mixture for a busted fuel injection assembly; throttle and fuel-injector.

Their recommendation? The European guru previously recommended in the earlier thread.

Purr-fect. So, after running it from 9:30a to 10:3a at the client's office, then going out there to restart it and run it around for 5 minutes to reset the temperature gauge to 81 C, then leaving at 11:15 (starting fine), driving at 1p to the mechanic and that was their conclusion.

After 1:30p, I noticed it was not wanting to start again. I had "intake sprayed" it at 7:30a this morning.

I guess after 6 hours it needs another infusion.
I asked this American mechanic does it hurt to keep methadoning it with "intake spray".

He said, "Guess not so much. But gotta get it fixed."

Their conclusion? Purchase the whole Fuel Injection with the 5" hole-pump thing".

$500 parts.
Who knows how much labor.

I'm okay with that.
I will have to ask the mechanic, if he is germanically-inspired...if he has grown tired of frau blondes.

Will post when he has time to answer.
Which would be a non-answer.
