What's the chances of a blocked port somewhere in the intake manifold? I know its not a clogged radiator, brand new one!




The only problem with that idea is it's surprisingly common for a new radiator to get half it's tubes plugged when a new engine sends all the crap from the cooling system into the radiator the first couple times the engine heat & coolant flow dislodges it... Blocks don't seem to get nearly as clean inside now that the EPA doesn't allow seriously caustic hot tanks.. Most shops use a hot water spray bath, some shops shot blast, but even then the blasting can't remove what it can't reach...
