W140 Stalls / Shuts Off IF Reved.
'92 400SE
Today we reached warm 70 oF weather and the following began to happen: When idling, I rev up the engine, then release the throtle, and all of a sudden the engine will drop below 600RPM and die OR come very close to stalling while it hesitates to stays alive. When I had it in REVERSE, I pressed the gas far enough to make it go above 2000RPM, the vehicle moved a fair distance and died as the RPM's were dropping. I waited a minute, and with the help of having the throttle pressed it came back to life. While in DRIVE, I have no problems. Recent services (500 miles): New sparks. New fuel filter. New breather hose from brake booster. Oil Change w/ ELF 5W40 LDX. Could this be signs of a vacuum leak...or a 100 other things. Ideas? ![]() Thanks. Last edited by slimak9; 03-28-2007 at 08:11 AM. |
