My 1989 300ce was stored for over a year and now it has a hesitation problem. It comes and goes. Usually it happens at take off. Today,I put in some Liqui Moly Ventil Sauber (valve clean). Then I ran Liqui Moly Engine Flush and changed the oil . I used Liqui Moly MoS2 10W40 oil and afterwards removed the resistor next to the master cylinder, Mercedes part # 000 540 24 81. I'm also going to change the spark plugs and air filter next. Anyone ever experience this problem?
