Got myself a 1987 260E. Overall car looks pretty reasonable....but the engine lacks all power at all. Foot the floor does close to nothing...

Swapped out the spark plugs so far and it solved the horrible idle (it idles nice now)...but I am still left with no power at all. To give you an idea... think 20second 0-60.

Should I look more into electrical or fuel delivery for the horrible lack of power?
