random misfire

Hi guys
Its been a long time since my last post, but i really need your brains and experience

heni 5.7 v8 2007 86k km p0300 random misfire
I have had to take the car to the stealership. they have checked everything and say it might be a cylinder head problem. the compression is good but it still missing on cyliders just one side of the engine. they are going to try a chemical decoke thru the intake as this is a cheap option compared with taking the cylinder head off. I still think it could be an electrical (ecu) problem.

have any of you guys had this problem or can you come up with any suggestions (dont trust stealerships)>????????:confuse d:
