Engine Performance problem
1987 Mercedes Benz 300e 6 cyl Two Wheel Drive Automatic
Had a problew that when cranked up car ran rough and bogged down when you stepped on the accelerator. Took to my repairman and he cleaned the throttle body and replaced the fuel filter (he said it was so clogged he could not even blow through it) After I picked it up it started great and ran great but now twice since I picked it up it has done the same thing, rough idle once started, and instead of speeding up when you step on the acelerator, it bogs down and stutters (hesitates) like when you cranked it up some how everything is out of whack. When I let is sit (turned off) and try again it starts right up and runs fine. Could this be an electrical problem and not a fuel problem? I just dont know. Can you help.
