Default Driving along car starts sputtering and quits running

I was driving along and car starts sputtering and i noticed some smoke coming out of exhaust, I looked at the A/F gauge and it was setting on 10 and didn't change. I made it a mile down the road and it quit. I looked under hood and noticed the ground wire that bolts to the front rt side of intake had came loose so i bolted it back on. Car would not start but i cold smell gas. After having car towed home a buddy said to replace the crank position sensor so i did and car will start now but still sputters and a/f gauge reads 10. I have spent 3 days searching and reading posts about to give up. I appreciate any help you can give.

Just changed COP back to stock coils and no change it still sputters and you can smell gas. Could it be a bad cam sensor or timing is screwed?

Was the ground for the ECU? And have you fixed it?

What is this a datalog of? Are you just free revving in your driveway? I see it idling...?

At first I was thinking - wtf is going on with your VE table...and then realized you were table switching - but in this datalog, it's irrelevant since you're on VE table 1.

If you look at VE table 1, can you reduce the values to see if the AFR changes? So far I just see it hanging in VE table 1 which has odd values...but VE table 3 looks like more normal values. It seems that it's set to switch via "Hardware"? What hardware?
