For starters it's an 02 m6 ss, headers and intake most free mods, ftra so on, don't think that's related
Earlier today my friend helped me put corvette o2s on because my ses light was thrown for o2s and the p0102, so we got the brand new o2s on than went to tackle the p0102, it had the usual symptoms, locked out of reverse and so on... We searched online and saw to check the eng sen fuse and god I was the happiest person ever to find that was the problem!!!
Than later on we were hanging out at the usual spot and some new guy showed up and he wanted to see my ftra so I pulled my lid off and showed him than got in my car and headed home, not far down the road the car idled rough from the dig and it slowly started bucking and than it got super bad almost not driveable, I could tell it was misfiring and dropping cylinders so the first thing I did when I got home was look and see the lid wasn't seated properly with the maf and I though whew that's all it was, I hooked it back up, started the car, still ran terrible, pulled the fuse, that was fine unhooked the battery waited for it to reset and restarted it, still ran terrible, it's throwing the light but I'm not sure what ill try to find out tomorrow, but does anyone have any suggestion? I looked at the Pcv hoses and all the vac lines they all look ok and nothing's been touched, idk

In order to properly diagnose this with little headache you need a scanner to see what is going on and what your o2 sensors are doing and what codes are being set. I would suggest getting it rescanned to see what code its throwing now.

Disconnect the maf and see how it runs. If it runs fine i could be the maf.I would think it has something to do with your lid since that is when the problem started.

We'll I deleted the p0102 code today I changed the fuel filter, it was the stock one, than I seafoamed it and drove the pants off the car for a little, no more misfire, but now I'm getting a p0171 bank 1 lean light, it idles rough and my exhaust is rattling, I plan to check the headers to see if they're loose, could that cause it? Thanks for the idea about the maf I'm gonna try that to, my friend said it could be because the maf is descreaned

A code P0131 may mean that one or more of the following has happened:
Faulty o2 oxygen sensor
Short to voltage on O2 signal circuit
High resistance or open on O2 signal circuit
The P0171 means it's running too lean, probably caused by the part that's setting the P0131 code.

Well I've taken it to a shop here and the guy says the drivers side o2 sensor isn't going to closed loop we've already swapped o2s, pcms,checked ohms in the wires and of course searched for vac and exhaust leaks, idk what else it could be =\
