You should have a pcv system. There must be a place on the valve cover for a pcv valve. If there is get a pcv valve for that engine & a piece of vacuum hose to conect it to the vacuum outlet. Adjust the idle speed screw to a normal idle speed & adjust the idle mixture screw clockwise till the engine slows down a little & back it out to smooth it out.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
