Hi. My 1997 c240 wasnt ticking over right.....a bit lumpy. I took it to a local MB specialist that told me there was an air leak on the inlet manifold and maybe it was a faulty plug or lead. They fitted a new gasket on the manifold. Now its running too fast and a little hotter than usual. They now want to have it in for the day to "have a good look at it" and find out which plug or lead needs replacing! Does this sound right? I'm not a mechanic but it sounds a little dodgy to me. Does anyone think I'd just be better off fitting new plugs or leads? Its a job I could do myself!
