Ok the guy in Florida is going to give you guys a lesson on Altitude and engines. The only thing with curves in Floida is our women. :lol:


In carbureted cars the mixture dosn't change automatically with the changing oxygen levelings. As the oxygen levels deplete the engine runs richer and richer losing power. The only way to get around this is to get out and adjust you mixture on the carb or install a mixture control knob like you fnd in older airplanes. With fuel injection the O2 sensors and mass air flow sensor tell the system how much are is avalible and in return it either leans or inrichens the mixture going into the motor. You do loose horse power no matter what but with fuel injection you loose alot less.
