2001 Lexus GS300, ECM/Inputs/Outputs Waveform
Posted to the Waveform Library on 12/21/2012

2001 Lexus GS300 came in for P0300, random misfire. Lacks power, will stall out with any amount of throttle opening in closed loop. On snap-throttle pings horribly; won't even break 2.9V peak. For this reason, I am calling this a bad MAF sensor.
