ok everyone. my internet messing up andi havent been able to respond. this weekend me and my buddy from the dealership did both of the gaskets, elbow,valve cover gaskets and changed the oil. i went ahead and did it because the smoking from under the hood from the oil and coolant wuz unbearable. but im able to say now that all residue has burned off.
i also have better news.since the new gaskets, now the car runs wonderful with no misfire when engine is cold. but once its up to operating temp, it misfires again and the exhaust pops.
now what i have observed is the vaccuum on the throttle body that feeds the fuel pressure regulator and something else has a terrible crack in it. it already had the crack but after we took the top end off its worse to te point of hearing the air hissing. so say the vacuum to the FPR is the cause, why would only one cylinder misfire?
