It wasn't to bad , I did most of them from the top and only used the slp plug socket i bought once. All the others i did with a regular plug socket. The wire routing was not the easiest but its not impossible. The only problem i had was #8, I got to it with the starter out but when I tried to remove it it loosened and then started to tighten back up after about two turns. That makes me think it was possibly cross threaded so I tightened it back up and left it in for now. So this leads me to my next question, i changed the plugs and wires and the car runs better but I still have a stumble in acceleration from first gear and a bad stumble in 6th gear at around 60-70 mph. Id like to know opinions on possible problems.

I hooked the car up to an oscilloscope and the engine is firing on all cylinders and all plugs and wires check out good. The car idles fine, If you give the car light throttle it revs normal. One you give it mid to heavy throttle it misses and pings. I thought it might have been some bad gas so I drove the tank empty and refilled and also changed the fuel filter. Could this be a possible opti problem ?
