[jeng22]

hi, my tags are due at the end of the month and i needed a smog, problem is i can't get the srt to set, followed srt driving pattern procedure to no avail, car has no cel and drives with no problem, did the headgasket 3 months ago and have driven the car for almost 4 thou miles...heard that early obd2 nissan vehicles are the hardest one to get the srt to set, has anyone experienced this kind of problem, looking for any advice or suggestions,

SRT:

catalyst- not readyegr system- not readyevap system- not readyO2 sensor- not ready

comprehensive comp- readyfuel system- readymisfire monitor-readyO2 heater-ready

i need to get one more READY to be able to have the smog done..

any help or suggestion is greatly appreciated, thanks
