.Hi all. I just picked up an 1985 300D off craigslist. I need your help. I've searched and read some IP stuff here and plan to read more.

Here is the deal -- has 298,000 but has been immaculately maintained with all records. What it does is idle rough and not get any power until Wide open throttle. Like if you have foot half way down, nothing, 3/4 -- still nothing floored -- engine starts to rev up. Also, there is no sign the turbo is functioning. I can't hear it at all.

I notice the fuel/stop lever on engine seems to be resting toward the "stop" as it idles low and rough until i pick it up with my hand. I think that is out of adjustment or something. When i pull it to rev engine -- I have to pull all the way till the IP throttle mechanism hits a little pin and the engine will rev high. So the IP seems to not be giving fuel until at WOT.

Any ideas ? Looking at it i see that the idle can be adjusted with the deep socket 14 and a screw driver. However the paint is still in tack so i do not think that is best place to start. Anyone have any ideas what the best approach is? In the meantime, I'm going to do the banjo bolt cleaning and stuff first.

Thanks
