Shakes or Wobbles problem
1983 Other Mercury Models 6 cyl Two Wheel Drive Automatic 130000 miles
This is a 1983 Mercury Zephyr that recently shakes when starting the engine in the mornings and stalls at stops if it hasn't been driven over 30 mph and warmed up. The engine was cleaned with engine cleaner fluid and oil recently changed. About 18 months ago it had a full tune up with new spark plugs and fuel pump.
