Back by popular demand, let's see what you did this week with your scope. Rules are, keep it clean and no hitting below the belt :)

Pretty uneventful scope week for me. Found and repaired a bad fuel pump on a TBI Camaro. [1991 Chevrolet Camaro RS, Fuel Supply Waveform] Pump turning 3700 rpm and pulling 1.8 amps. New pump [1991 Chevrolet Camaro RS, Fuel Supply Waveform] turning 8683 rpm and pulling a touch over 3 amps. Customers complaint was lack of power. Fuel trims where way positive and fuel pressure was 10 psi at idle and would fall off on acceleration O2 would would fall to 0v at WOT. New pump solid 13 psi. I have a FLS valve issue on a 2000 Mitsubishi I will post later I will post later.
