This video illustrates how a chassis dyno and the proper testing techniques were used to identify and repair a fuel delivery problem on a 74 Pontiac Firebird. (Note, this is an orignal owner vehicle which is a very nice clean vehicle that still looks like it did back in 74!) At the end of this video we show a chart with fuel pressure, flow and wide-band air fuel ratio measured during the final tests on this vehicle. The vehicle was in for repair back in 2012.
