I only notice it in 2nd gear, because it raps out so quickly in 1st, and i never go fast enough to get to the top of 3rd
Yes i have a tach.
It happens regardless if the autotuner is installed.
I'm betting i have worn out plugs or a weak coil. I doubt I'm low on fuel pressure, because it doesnt go lean. If i had an actual spark leak, it would misfire under heavy load at low RPM's.
Im going to check the fuel pressure and replace the plugs/wires as a start. I also might put the wideband on the other header to make sure i don't have a bad injector.
