engine down on power engine missing under load
 

started my 1983 930 this morning and noticed it was harder to start. it did start and idled fine. when i started to drive i noticed it was missing like it wasn't firing on all cylinders. not a bad miss but definately down on power. i drove for about 10 min. and it felt like it was getting worse so i drove home. it ran fine the last time i drove it. i have an electromotive distributer less ignition. the only thing i did between the last time i drove it till now was to run wires from the starter solenoid to a push button switch on the dash as i was having intermittent starter issues. i tested the starter several times without having the key switched to on(my fuel pumps come on when the key is turned to accesory. could the engine have been flooded while i was doingthis? does fuel squirt in everytime engine is attempted to start? maybe i fouled a plug. any help would be greatly appreciated. another issue i've been having is i get blue smoke out exhaust after car is intially started after a couple of minutes idling then it goes away. mechanic said turbo end play was fine and the there was a trace of oil in the intake(engine oil is not overfilled
). what could be causing that? thanks in advance, mickster
