Stupid Cylinder 4 misfire 304

[datmfmac]

Ok I had the dreaded lifter collapse after hearing it tick. We tore into just replacing the lifters, gaskets, things of that nature. At this point I don't have any ticking noise but still a misfire, and this is after new plugs and wires, new ignition coil. Somebody please hellpppppp

A little more information like what year vehicle you have and what motor is in it, etc. makes it a lot easier to offer suggestions.

Also a list of exactly what parts were replaced would help.

Moved you over here from Site News for now until we can figure out what year you own. Site News is only for the site.

Good time to check the plug again too.. I once cracked a plug during installation..
Though it sounds like you probably changed all the ignition stuff chasing the misfire..
