Please help I’m new to owning a 80 series, and I have a small problem I cannot figure out. So upon buying this 1997 lx450, it did have a small hole in the top of the fuel tank, I patched it and and pressure tested it and while I was there I threw on a new fuel pump. I also installed new spark plugs while I tended to installing new valve cover gaskets. So here is my issue, when I crank it, it starts right up and idles at 1000 perfect no issues for however long I want to leave it running. I put it in drive and start off slow and easy it shifts fine and drive perfect one I get a couple minutes down the road mainly when I let off the gas and it tries to down shift the RPMs will bounce like crazy and it tries to go down to zero and stall out, if I hammer the gas it saves itself and keeps driving. Sometimes I can just hammer the gas and let off and cruise and it’s fine. When the rpms bounce it does a little jerking as well. It seems like maybe it’s a fuel issue. If I leave it in park and keep it at 2-3 RPMS it will white smoke a little and then the RPMS will eventually try to drop out. It had a code for both O2 sensors I replaced them although the only ones I could find didn’t look like the ones that come out of it but the harness fits perfectly and it bolts right up. But every time it does stall out and dies it gives me the same code. Any help will be appreciated please and thank you! I’m not sure how to post or attach a video to show what it does but if someone wants to reach out maybe I can send it another way
