Sorry not much luck searching. I have an 82 300d. I had been have rough idle hard to start and car wouldn't idle till car was warmed up then idled fine also low power whentami g off. I Car has 215,000 miles on it and as far as I know never had nozzles changed. I first cleaned fuel tank, purged the fuel system with moly purge, changed filters, Checked the valves. While I had everything apart did compression check which was a cold engine and all cylinders checked around 300. I had the nozzles rebuilt by a local shop and they told me 3 of my nozzles were bad when they got them. Since then I put it all back together and now the car will start good and idle. But when push the peddle down doesn't really rev up at all. Once start driving the car seems to have normal power and drives fine but it takes till car gets up to 10-15 mph oR so before really seems to start running right. After installing rebuilt nozzles I had to adjust my idle because it was low. Now 2 weeks later it seem slow again and the power issues is still there.

Think might try to get a another set of heat shields and check compressions when hot. But wondering if it's bad rebuilt nozzles or possibly bad injector pump. I have the stuff to rebuild turbo. Maybe possibly waste gate issue just not sure where to go. Can def feel it kick in when it's starts to recover. Even once it's warmed up hard to rev engine with peddle

Any advice would be greatly appreciated.
