Gutted pre cats today...and yesterday.

Touche. But tha'ts what the computer says I start rolling it works its way up from 13 to 16 or 17 then I stop and it goes back down, this only happened after gutting those damn cats before that I got near 19 city and id cruise at 85 at 2800 rpm getting 31 mpg. So something is jacked up and i'm not liking it. Like i'm really 100% regret doing it. I loved my car more than my family and now I want to get rid of it, don't think y'all realize how much this ruined the car for me. For god sakes I broke my EFFIN nose dealing with this pile of horse pucky!

I have a 180k, I re used my old gaskets for the y and the front header manifold and I wasnt sure about to toque specs so me being tired and lazy at this point just tightend them till they were decently tight ( at this point I was afraid of snapping a stud on the head.) could this be caused by a bad exhaust leak? cause when I start moving my mpg goes up to 16-17 ish but at idle it goes to 13s. Also the front pre cat (which is gutted) only has 4 out of the 7 bolts holding it in place. And to add to your tidbit I drove over 15-20 miles on open headers, I even opened it up for someone in a civic who thought he was king of the road.....im about 90% sure he shat himself and half of Franklin tn now thinks I have an LS in my car....
Umm,,, ya think?

Need some advise here,
I gutted the pre cat's a few weeks ago and now I've been getting the PO420 code (bank 1). I'm sure the car is running lean too, the spark plug from cylinder 4 was really dry when I pulled it out and the car runs rough when its hot. Anyways since I gutted the cat's there's less restriction which is throwing this code correct? Does bank 1 control the fuel and air ratio which is causing it to run lean? Would getting a new sensor fix it?

No I don't smell fuel, but does the 02 sensor control the air & fuel? I'm running lean because the spark plugs in the front are dry, I also get a rough Idle that I think associated with fuel ratio. I think the new NWP spacers may have played a small part with changing that mixture too.
I've had the ecu and fuel/air ratio reset with the Consult 2
