Changed fuel filter today..
 

Everything went well, up until I tightened that banjo fitting from the fuel pump. Damn that thing takes a lot of torque to seal!!? used the new copper rings that came with the filter..

I noticed two things, my idle speed is about 150rpm higher than before I changed the filter (@80*C)
and I noticed a marked improvement in her ability to haul her heavy ass up hills, after filter change..whereas before I'm downshifting every time I go up that hill. (2 or 3% grade @50KM/h)
Miss at idle is still present...still slow on 0-50kmh acceleration, but the agony is slightly reduced...
I'm now 58% convinced that my ignition system is causing the miss..
