also 3kgt right i would defenately think you'll fail emmision on a dead hole ... or how is ithe cylinder fucked ?
my bad, i read it wrong. i was thinkin hes having these problems and trying to diagnose like he failed and was wondering if it could be a bad cylinder, which is possible but i would doubt that because u would probably notice it without having to get it tested and so i woudl think it was somethign esle first. if u know u have a *bad* cylinder then i would say its very possible ud fail. like smokeem said if we knew what was actually bad about it then it would help
