I recently had to do an intake change due to a leak at the thermostat housing I decided that I would go with the Dorman intake. This intake has the aluminum crossover the gaskets are pre-installed alternator bracket and thermostat with gasket. It was an easy job not to difficult. The problem I had was when I started the engine for the first time was the engine idled a little ruff but the problem was when you increased the engine rpm I was getting a back fire. I talked to J.
and told him he recommended that I check the plug wells and make sure there was no coolant in the wells. Of course there was so I blew them out with an air compressor and reinstalled the plug wires it idled better but still back fired when revved. I was p****d at this point and decided that the plugs and wires where going to be replaced (since they had 40,000 miles on them from previous owners record). Well after removing the wires I started removing the plugs and was surprised to find that the plug on bank #1 1-4 was running lean and bank #2 5-8 was running rich all plugs had various deterioration of the electrodes. When completed the I started the engine and boy what a difference the idle was smooth the back fire gone and power that was lacking is back and it is running like a champ. To bad when the DOHC is done that engine will be history.
