ok so i let me motor warm up then do a compression test from left to right 209 210 210 213. put plugs back in and it set for a while. my g/f wanted to see how it works so we pull plugs and do it again, put plugs back start car and hear ungodly knocking. so stop motor start again and it was still knocking pull plugs and number 3 was TKO. black as can be and the part that you move to gap was like a half an inch gap and pushed to the side. anyone know why this would happen i put new plug in and it ran fine after that. i have pics but dont know how to load them.
