Re: 4.3 vortec V6 running terrible
So everything I have read so far leads me to believe the truck should run fine without the cat. Yes one can argue about performance and the check engine light and all that but from what I have came up with I don't think it would cause it to misfire. Unless someone can tell me otherwise. Also I do understand that a clogged cat will cause an issue but since my cat is now gutted that's out of the picture.
I'm gonna be posting a video of the truck running so you all can hear exactly what I'm dealing with.
