I am sorry for the long waitso this truck ran fine before you removed the secondary air pump ?you just remove the pump and the tube at each manifold and blocked it off and now its doing this ?are there any codes set at all in the computer ?
Customer: replied 2 years ago.
I removed my secondary air pump tubes from the exhaust manifold and made some metal blanks to cover the holes in the exhaust manifold because the rubber like connection began to melt and leak exhaust gases . So I thought I could just take off the air pump tubes since the air pump had been disconnected before I bought the truck, the tubes have termostats in them that went out and let hot gases out when they weren't suppose to and that s what cause the melting. The truck ran great up untill a week ago. I haven't had it hooked up to any diagnostic equipment yet I can t get it there the truck won t accelerate I give it gas and it bogs down it doesn't quit but it won t accelerate.
