Idle problem need help

I mentioned this in my response above. The timed port is for emmissions controlled engines. The untimed port is for non-controlled engines. Use the non-timed port and set your timing before connecting the hose (block the hose off at the distributor end before setting the timing to stop a vacuum leak). The brake booster hose doesn't effect the timing so you can leave it connected. Once timed, reconnect the hose and set your idle speed. All cars drop some idle speed when set into gear.
