What happened to the other thread. Any way, can some one confirm on the O2 simulator fixing this problem? Can it also pass inspection with this simulator.

any sensors wont be covered.

checkout time is usually one hours labor to cover diagnosis. basically, you sign for it, and if its not a warranty issue, youre stuck paying it, its usually applied to the repair.

Ok thankyou evryone went to dealers they fix the converter change gasket and something else total of 4 things and no charge. I have to convince them first with ecu upgrade was done so they said we can;t do anything else after that i said 8 years / 8K warranty nissan he said hm.. called serveice manager i expalind 8/8k and tsb all this is covered then he say you have to pay for all the sensors i said just do the warranty work only he insisted that i have all the other work done approx $2000 i said you crazy money don't grow on trees. Then I pulled out a print out of federal law on emmision stating 8/8k guess what that did the trick after that no problem he fix the car 3 hours with 4 new parts no chrage great finally i got the dealer to fix it for nothing wow

thaNSK TO YOU GUYS I WOULD HAVE END UP PAYING FOR ALL THIS WORK
