What do you think of my Graph? I cannot fig out my bucking issue for the life of me...next on my list: bad o2 sensor, UIM/LIM gaskets.




Like I said, you and the other guy both need to change plug wires first. I have probably 6 dyno graphs all of which share things in common with you both and all of it was straightened out by plug wires.
Some of my symptoms:
-misfiring like crazy then clears up as rpm increases, very jagged dyno down low but smooth up top.
-random misfiring throughout the rpm range leaving the torque curve looking like a saw blade.
