After fitting extractors and new exhaust my 4.8 has developed a miss. It goes fine when you are up it, but misses up to half throttle under 2500 rpm. It's still very driveable, dut very annoying when you slowly apply the throttle.
It has been on a scanner and there are no faults coming up. I replaced the plugs yesterday to no avail. All coil packs look good and I have checked all the electrical joins I could find.
Any ideas?
