ok, first let me say, you guys have all helped me very much and i still am learning about these cars. so here i go... my car still has misfires in cylinders 3,4, 5 and 6, not so many in 5 and 6 but like 3,xxx in 3 and like 5,xxx in 4, i changed plugs and wires and it helped the other cylinders a little but its still bad in a few as well. my mods are as follows, k&n cone filter, ported and polished heads, intake (upper and lower) ported and polished s/c, 3.4 pulley, cat and res eliminated. it has no kr at idle but didnt take it out on the street to test it, just revved the engine. so my question is, does anyone have an idea on what may be causing the misfires? and to properly test KR do i need to drive it? thanks in advance!
