My 1979 280SEL
 

I just had my timeing checked on my car and a new fuel pump installed. Now I have a rouogh Idle it seems like the fuel distributor is not working right. My question is would the Kit fix the problem that I'm having? If I play with the gas pedal it will rev up. My mechanic said it's the fuel distributor. It's not allowing it to have a good suction through the intake. What are you guys thoughts of the situation?
