Well, I went out today, pulled the plugs, found all but #5 are burning perfect, #5 is not firing and was gas fouled.. because I had no new plugs, I swapped #5 and #6 and fired the car up, seemed to still be missing. I pulled #6 to find the plug was cleaned off and was burning. #5 was now gas fouled ( was a good plug in #6 ) so I knew somthing was wrong. got out my compression tester and tested cyl #5... 25 PSI, just to make sure my tester was in check, I checked cyl #1 and got 150 PSI.. I know it's ither rings or valves. going to go out Friday and get a leak down tester to check which it is.
