My daughter has a 1989 300sel(gasoline) straight 6. She purchased this car last year and it ran fine. We had a few minor repairs that needed done. power steering hose leak and had to grease linkage for the acceleration issues.
Recently, she has been having issues on startup. First she had to pump the gas. Then, she had to hold down the gas pedal. Now, this doesn't seem to work half the time. Once the car does start, it idles rough for a second then its fine and drives great after this.
What I need to know is if this is definitely the Idle Control Valve(which I'm replacing) or is there something else I need to look at.
I do plan on replacing the fuel pump, fuel filter, and distributor cap and rotor this month.
