1977 924 was sitting a while , installed a new fuel pump , cleaned the meetering block attached to air cleaner and cleaned out injectors -- car will start after 5-6 cranks (delayed start) and idle smooth , when accelerating at idle slight hesitation then revs, when put in gear and off clutch power bogs and engine stumbles, back on clutch idle is fine and will rev with slight hesitation again -- need some help new to older porsches

thanks

Check the entire intake system (from the air cleaner to the head) for leaks.

. . .and for those just tuning in, vacuum lines are part of the "entire intake system."

similar symptoms to when I had a small tear in one of my boots in the intake system so check them too all over under and behind, as I didnt pick mine up straight away and this gave me a rather large headache as I couldnt find the problem.
