I have searched this forum with key words that apply to my problem, and didn't find anything helpfull. I did read a reference to a idle selinoid said to be located on rear of injection pump. I looked at mine , there is something in back and on the side with a vacuum line going to intake , but dosn't look electrical . If I make it stay running by keeping RPM's up until it gets warmed up , it will then run smooth . I just bought the car and it had sit for a while, previous owner said a month ,but fuel that was in it seemed bad or old. The car has ran at least a hour on new fuel and filters. I don't know where to look next. Can anyone help? Thanks, Charlie Klippel
