Any suggestions of what to look for on a couple of issues with sluggish running 1982 380SL. It accelerates real slow, however moves good on top end (well it did), now it misses on higher acceleration. Any ideas, I did have new spark plugs installed when I had some issues with it starting at all and he may have reversed some of the plug wires. Appreciate any feedback of what to look for. Car has only 74000 miles. .
