wait, you have a front O2 unplugged???????? and that made it run better? Is that right?
Yes, filter is low & in the back - RH side IIRC. Quick release on one side, flare on the other.

Even with only 25 miles? That was such a PITA and I never want to do that again lol. My damn hands are too big.
Yes, the front o2 is unplugged and it ran a lot better with it like that. On my Jeeps at least, if the front o2 is not reading/unplugged, the computer will run a pre-programmed setting.
I'll check the filter, thanks!
