Exclamation Any help is needed on my 97 Tj!!!

Hello
Im in the process of giving my car a bolt on tune up so i started with wanting to buy a new o2 sensor. i bought it and installed it then my check engine light came on check engine light is on. i took it to autozone and they said it was running to lean and to get an o2 sensor.
even after the code was erased. so i put my old one back on. and now its still saying its too lean.
and my check engine light is on.

my light wasnt on before i decided to change the o2 sensor

i have a 97 tj 2.5 and im wondering what else needs to changed so this can be fixed

i have changed the exhaust
i added a short ram intake
i put a blue top opt
i changed spark plugs and wires
i changed the distributor cap
i changed the rotor
and i was looking for a pcv valve but i couldnt find it.

i need help to get the light out and get this jeep thru emissions

thanks

Disconnect the battery for a few minutes then reconnect and see what happens.

Interesting, I just came in after putting an O2 sensor on my '97 2.5. I got a Bosch from NAPA. I'm anxious to find out how it works.

If my CEL is still on after three to five key on/off cycles, I'll put an ohm meter across the white wire(s) pin connectors on the sensor. FSM says it should read 5-7 ohms. The probes on my meter were too big so I couldn't test the old or new sensor. I'll rig something and check them both if things don't work out.

If the sensor is good, I would assume there's a glitch in the upstream wiring. The circuit is described in 8W-30-2.

good luck
