Hi there, I have a 1987 190e 2.3 16v and just last week I was shifting and the gas didn't stop. As I depressed the clutch and took my foot off the gas the engine just revved up crazy like, as if the gas pedal was stuck, but I don't really think it was. This happened again the other day and I could not get it to stop for about a quarter mile. Any ideas? Don't want to burn up my clutch. Thanks!
