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
