triple a good news is it looks like i didn't disturb and vacuum hose. compu85 the car shut off with no problems before i started playing mechanic.it just stalled at certain times. so i'm thinking the ip is ok and it just the basic idle setting but how do i adj if the car shuts down when i pull the plug on the acuator? do i increase the setting on the back of the pump while the car is off? trial and error? do i keep adjusting until the car stays running while the acuator is off and then start fine tuning? i don't want to blow the thing up!!!
