Lean on bank 1 when I fast rev it sounds like I'ts choking

[Hitek]

Ok i first had a code for a vacuum leak now fixed. My main problem now is after i fixed the vacuum leak it runs ruff if I lay on the gas quick or rev up fast and let off quick. I put some transmission fluid in the gas tank and it cleaned my fuel system. but i had a problem before and after i did that trick all four of my plugs on the exhaust side are wet when i pulled them out. the right are just fine, they look like there getting a good burn, is it my c02 sensor or my cat?

I had a code of p0171 and p0301 and p1443 , after i cleaned my MAF and and replaced some hoses i now only get p0171 code and of course all my left side plugs are wet. I took the intake connected to the manifold, that was a pain to get the bottom two bolts back on, never thought they have to be perfectly strait in order to screw em back in, took me a bit to figure that one out deep socket don't work, hits the valve cover

Ok it was my coil, some how i must have broke the connection when i pulled the valve cover off, Which was a pain in a halve. I still have a lean code in my fst bank and now when i rev it up it stutters when it cycles down, and when its at hi rev, I can hear the missing in one of the pistons.

If i give it a fast rev it like I'm choking it too much

P0171 code is usually a bad MAF sensor. it tricks most people into thinking it's a bad o2 sensor though.

hell, here you go:
