ok so i checked valve clearances and all were in spec except one or two were slightly over. i replaced plugs and set the gap. checkled compression while i was there and got 170-180 in all cylinders. still sluggish all around though. i used to be able to burn out in second by just flooring it. now im just like a normal crappy car.
