OK so I am working on a GM 5.3 L that has active fuel management and I suspect that my number two injector is not flowing enough you’re causing a lean misfire .. I follow the calculations and get 6 .. not Sure if that is good or if that is bad it says that it should be within 20% but it doesn’t tell you within 20% of what number is it within 20% of the total pressure drop or 20% of the cylinder that you dropped from the equation
I believe you do not want a variation greater than 20% across all cylinders. This would have you compare the highest and lowest, then express as a percentage.
Top video. Very helpful.
Very informative
Thank you!
