'95 C280 went in for 30K service. Came back
with a sublime tumble while idling in drive and neutral. New spark plugs. Mechanic said he 'scoped' a wire going bad but did not change the set until I would tell him when problem got worse. So, now (1 month later) the engine idles with a more pronounced single intervaled tumble (misfire?). I wonder if mechanic may have pulled wire to a spark plug and damaged wire ? Benzmac archive states that MBZ plug wire are good quality and the metal ends can be changed. I don't feel its right to spend another $200 for new wire set and labor. I wonder if the spark plug gap is correct. Could this be the cause? I want to check it before giving it back to mechanic. It idled fine before the 30k service and after, it didn't. Ideas? comments? Thank you. p.s. not dealer but indep. MBZ shop ------------------ 1979 300D 133K miles 1989 300SE 1995 C280 |

I would be interested to know - from the techs - what effect incorrect gaps have on an engine performance also. I was asked that as a question at a 4H event I was entered in A LONG time ago. I do not think I answered correctly.
thanks, engatwork |
