I have a 2000 ls V8 w/ 70k. About 6 months ago I had a CEL light come on and it was a cylinder misfire. I had the valve cover gasket, plugs, boots and 2 coils replaced (all on 1 side, 1 and 3, 2 had been replaced previously). This fix did a little to help and now the car is shaking at idle and hesitating between 42 and 60 MPH(like it won't go into gear). I can also smell an exhaust type smell when any of the vents are turned on (heat, ac) that seems to be coming in from the passenger side engine vent. I have searched here and have found a couple of posts w/ similar issues but no one seemed to have a resolution. My mechanic seems to think that the coils are all fine (don't know what tool was used to check). What else could be causing this? The shake is coming from the engine but could it be tranny related? I would really appreciate and help. Does anything kick in at 42 MPH?
