Put some premium or high test gas in the tank and a can of Seafoam. Take it out for a good drive. Sitting for a year or so will cause the old gas to varnish in the fuel lines and injectors. Whyen you park it again, make sure there is NO regular gas in it. Regular gas with ethanol will create havoc with an engine that sits. It makes water.
ok well that is my next move hopefully thats the problem
You could do a compression check as well. It's possible that you have a sticking valve that the Seafoam didn't get cleaned up.You could also be experiencing a lean burn on that side. An engine that runs lean on fuel will run exceedingly hot, so it is possible that there are blockages or restrictions in the fuel passage/injectors going to that side.
