1991 Mercedes Benz 500sl Repair Question
Mercedes Benz 500sl Engine Problem
Typically, this problem has persisted for a while wherein on cold start-up it runs fine to any distance but once the engine is shut down and left for 15-20 minutes starting is a problem, running unevenly and occasionally misfiring.
Previously starting after 15-20 minutes was not such a big problem but the engine would stall and run unevenly. Recently this problem has aggravated where now starting-up is a problem
Man, this question is like the plague. Its everywhere, with no signs of retreat. I hope this helps. I've got the same car, 177k on it, and when I bought it it had the same problem.......I've literally dumped close to $8,500.00 all of which began with the BRAKES. Yesterday at noon I basically had a brand new car that ran like shit. Frustrated, stomping on the brake pedal, I heard a new noise, a "pop".??? Now what the fuck, I thought, as my idle leveled out at 550..a few moments later my#3 and#6 cylinders slowly came to life. Within 5 minutes the only indication of a running car was the tachometer. opening the hood revealed an oily mess of smoking brake fluid. Apparently the jackass who did the brakes compressed the last caliper and failed to siphon the excess fluid. This minor oversight completely FUCKED my vaccume system. Affecting everything from the trunk latch to the timing (not literally). This morning I turned the key (yes its new also) and after a minor mixture adjustment gleefully smashed the gas and stuffed 315 horses into the almost new Dunlops for about a block and a half. This ticket pales in comparison to what my brakes cost, and I saved money doing them myself!

Oh, as for the battery, in the trunk under the latch, facing forward (there may be a plate or cover over it) there is a yellow lever that dictates we whether or not the trunk light comes on when the latch is released. Its for oversized cargo, flip it to the drivers side, correction, left side if looking forward. The factory grease gets hard and eventually it sticks only to come on when the ignition is on. please don't ask how much that little episode was worth.
