The engine is running to rich and the truck runs rough and the exhaust is cherry Red. their is no Catalytic Converters.
Has the engine lost power? Retarded ignition or valve timing will cause the exhaust to glow red and result in dramatic loss of power. Rich running conditions causes cat converter melt down. As Bret said trouble codes will determine the diagnostic path to follow.
I have a 1997 f150 5.4 triton, now my exhaust isn't red but my truck runs very rich. You can smell the gas in the exhaust. When its a little cold and rpms level wile drive to 1200, the truck almost want to die but then shot off like a rocket. ? I just do get it
