Question about 1998 Nissan Altima
That's hard to say without a little more detailed information ! Was the check engine light on ? If so what codes ? There are a lot of reasons for not passing a emission test ! The engine management system is very complex an has several sensors that input voltage info to the engine computer, which in turn controls out put devices . injectors ,purge solenoid , shift solenoids , idle control etc.. No I could say with the information you supplied ! PA EMISSIONS WAIVER
