Thanks, that's a good idea. Unfortunately, I don't have a pressure gauge and adapter for the fuel injection system. And you're right, I've had to richen the mixture to get a decent idle and throttle response, so this may be a case of the cure being worse than the disease. Thanks for doing my thinkint for me.
1986 560SEC: 150,000 miles, runs great, but I've got to sell it (too many cars for one man)
1987 560SL: 122,000 miles, used to run poorly, now (thanks to forum), runs great!
1997 GMC Jimmy: Turned out to be a turkey.
1989 T-Bird Super Coupe: 150,000 miles, still runs great. Ford got it right.
