I had a fun time at the mechanic today testing the fuel pressure values of my car and expecting to find something seriously wrong. Here are the results, I converted to lbs as the mechanic didn't have a fuel gauge with "bar" on it: measured (spec) Control Pressure: 55lbs (49-55) Primary Pressure: 70lbs (71-79) Rest Pressure : 43lbs (47) - 10 mins later : 39lbs (24) Everything here seems to look ok to me, if not a little high on the control pressure and low on the primary. Where should I start looking to solve an extremely rich fuel mixture and a consitent backfiring? I've already adjusted the CO2 screw to the leanest that it will run at. Thanks!
