P0300 I've been getting the P0300 code (random misfire) every 20 miles or so & have been clearing it. I failed emmissions today because not enough miles/time since the last clear. The guys at the test place said 10 days of driving before I bring it back. I disabled that code so it won't come up again. How far, how many trips will it take before I can test again? I'm using HP Tuners & assume it will be when the "every trip" diagnostics all read complete. The test guy also commented the car was "bad ***"
