When the car is in drive it starts to idle a little rough. The same goes when you put it in reverse. When in park or neutral is runs smooth. Also when accelerating it runs fine, this only happens at idle. The quick fix has been to clean the wires that connect to the injection pump, and that fixes it for a day or two. Noticed that the hard metal fuel lines that deliver fuel to the injectors are wet on the pump end. Not too familiar with this but i have read something about some o rings that go bad and let air in. Not sure if that is what is happening, or if there are other issues
