Hey guys, bought a 1985 500SEL us version about a year ago. Car sat for about 10yrs. New fuel filter, pump, sparkplugs and drained old gas and got the car running. However when i drive the car it has no power, if i stomp on it the car accelerates about like a old ford pickup. I have faster take off in my 350SDL! Not sure what all i should check. Since its us version i plan on removing both cats which will should help. Im curious as how to bypass the 02 sensor? My assumption is a resistor or very simple circuit would do it. I also understand that these cars have a timing retard resistor for us version. Not sure where it is but since i run 93octane I think removing that would help. And someone suggested a fuel distributor rebuild to me. Anyone have any good suggestions? Im selling the car to a friend and he needs it within the next week or so, so id like to get this problem resolved asap.
