Check engine... 435 (front O2 sensor SLOW) 850 1995

It's best read via scan tool but it'll read normally as it should (compared to OEM manual specs) now when tested as you're not getting any fuel trim codes, so it's within range BUT has been operating slower than normal. The only way I know to cure THAT code is by replacing the front O2 sensor but try driving it for a while as maybe you'll be lucky and it won't return.
