Ok guys/gals. I bought a nice little 300D for my son and I to mess around with and enjoy. It was a hard start but ran geat once it warmed up. We brought it hm, changed oil and all filters. chased a few vacume leaks etc. Drove it for about 150 miles no problem. later that night went to the store and on the way hm it bogged down and would hardly move. I nursed it hm and am now besides myself. I check the vacume and off the booster it is irratic at around 15. none of the door locks worked and it ran on when I turned it off. I put Lucas injector cleaner in before the problem started. It will start hard but when it is warmed up it will idle and rev fine just when I try to drive.tranny fluid looks and smells fine.I have ordered the vacume kit from diesel giant and a rebuild for the vacume pump. I isolated the 2 yellow vacume lines runninng into dash and capped off now it shuts off right away. oh yeah it is a california car. Any Ideas??
