Thanks to the help from this site I have been driving this car daily. It starts up everytime and is a fuel miser. My issue is the idle hunts when the car is in park. It does this cold or hot. When its in gear it idles fine @ 850 rpm (which seems a tad high to me). Can someone tell me where the idle adjustments are and how to set them? Aside from that issue (and this one http://www.peachparts.com/shopforum/showthread.php?t=174224 ) the car is fine.


Thanks,
Dubyagee

What do you mean "hunting" idle?

The idle rolls from 850 to 950rpms twice per second in park.

When was the last Filter Change for the Fuel and air?

Both filters are new (less then 100 miles) and the primary fuel filter still has a white filter media. I recently installed a head gasket, timing chain and all related parts for such. I flushed the tank and the lines. The IP has new delivery valve washers and O-rings. The injectors have new nozzles and have been matched and popped @ 150 bar.

Then i'm not sure what could be. Hello other MB guys!

Ok, I'm pretty sure that the 1984 190D idle control is different from the later versions of the 190D. I think this came up on the MBCA forum and a search over there might get you something. I believe Dr. Booth has addressed this in the past. Best I can do.

This is from Dr. Booth. Hopefully the following post of Dr. Booth's will help. I hope I'm following protocol here for cross posting from another web site. Apologies to anyone in advance.


"The '84 190D doesn't have an overvoltage relay. Idle problems of a properly tuned 601.921 engine are usually caused either by the idle being too low (should be ~750 when the engine is warm) or because the temperature activated vacuum control system isn't working as it should."

I did everything that Pdf stated and it purrs now. I took her on a 300 mile trip today and she didnt skip a beat. I have an issue with a cracked injector line and a lying speedo (70 is really 81) but otherwise ran flawless. Thanks for all the help guys.
