Greetings,
Its a happy day for 2 reasons, first because my car now runs great and secondly because I get to give back to the group that has been so helpful to so many.
My 95 S320 started acting up a few months ago with a hunting and unstable idle both in park and in gear. I tried fuel injector cleaner, plugs, etc and no change. Then about a month ago I lost 5th gear. The mechanics said I needed a tranny rebuild (around 90K miles) so I scheduled an appointment.
Last week I borrowed a friend's scanguage tool to check the rough idle and the error codes pointed to MAF (P0101 and P0170). I tried cleaning it but no luck.
Today I installed a new MAF and idle immediately improved. I took her out on the highway for an "Italian tune-up" and to my surprise I regained 5th gear and it shifts perfectly upon acceleration and back to 5th as it should.
Needless to say I canceled the appointment for the tranny rebuild.
Hope that helps someone, Bob
