Good day all,

Just bought a 84 300d from a used car lot. Has 225k. The a/c blows cold and the car idles pretty well, shuts off well, starts easy cold or hot, no smoke, not much blow-by. The problem is that it is very slow from standing start until turbo kicks in, and with the a/c on car takes 2-3 seconds to respond when starting off. Trans. starts off in 1st(seems to shifty early though). New fuel filters(and redline fuel additive). The banjo bolt was plugged and cleaning helped some. Am hesitant to adjust alda until have exhausted other solutions. One other strange thing that is that the rubber fuel hoses going to primer pump and also "cigar" hose are visibly pulsating while engine is running. If you floor it it will get up and go, but in normal driving below 2k engine rpm it is a real dog. Slower than my old w110 190d. also gets really good mpg(33-36). Suspect it is running lean??? Does anyone have any suggestions? Thanks.
