I know there is alot of ASR questions on here. However, I have a 93 500SEL w/ 140K miles. Today, I was on the highway for 20 miles, got off, and when I accelerated, it went in to what feels like the Limp Home Mode. (Had that problem with a 94 I had) BUT NO ASR LIGHT. I turned on and off the car. That would always reset my old car. I did go to a car wash today, could something have gotten wet? Des anyone know what else causes LH Mode, other than ASR? Car runs great otherwise, and has plenty of oil pressure, etc.

Thanks
