I own a 1986 560 SEL. i loved the car car until it started flooding out when it warms up it runs great until then. it rolls out black smoke and i can hold the petal to the floor and it barely holds 500rpms. it used to come out of it after a few minutes and run fine again till it would do it again. but it just does it all the time. ive been all through this car racked my brain and those of others, i still have a few questions about it. Ive changed the fuel distibutor 3 times im going to cross it with another mercedes to check it so but i dont think thats the problem ive changed the spark plugs it just fouled the new plugs. i put a new fuel pressure regulator and a used vein position sensor in and it stoped doin it for a while. the filter was changed before not sure how long ago. I think ive narrowed it down to electrical, im not sure though and im not an expert. any advice?
