I just got this boat .Its a 26.5 foot chaparral . it won't idle . sometimes it does . changed plugs, plug wires cap rotor. I have to give it a little throttle to start it. sometimes it will stay running. but most of the time not . the more throttle trying to start then it wont start/. It seemed to be doing better but then all of a sudden it started running like it had a miss and now it is terrible. I tried a aftermarket iac valve no change. the idle raced for second then came down normal but then died and wouldnt start so i put the old iac in. Im leaning towards fuel pumps and fuel injectors. salt boat from florida in fresh water now up north. could the change in sea level do anything. thanks for any help.
