chappy Posted April 27, 2008 Share Posted April 27, 2008 I just got the pathy ready for inspection "sniff test this time" by replacing both of the infamous resonators that nissan wants 700 a piece for got both for 300. I also finally fixed the evap b.s. that I had infamous p1491 vacuum cut valve bypass valve 106$ (sucks for a little piece of plastic that has a metal housing 2 hose ports and solenoid). I reset the code after all was said and done by disconnecting the batt for a little bit and so far 60 miles no code. Normally after resetting the code the ses light would come on in 16-36 miles I just don't know if there is a drive cycle that I need to follow before getting her inspected I just don't want to get rejected for lack of emissions data, do any of you guys know the cycle for evap after a reset? Thanks guys. Link to comment Share on other sites More sharing options...
HankG Posted April 28, 2008 Share Posted April 28, 2008 You were right about having to do a drive pattern before getting it tested; I failed the first time because of that. This should be what ya need. http://pages.suddenlink.net/hank-g/drivepattern.jpg Link to comment Share on other sites More sharing options...
chappy Posted April 28, 2008 Author Share Posted April 28, 2008 Passed no problem just mixed highway and stop and go for 75 miles and idle for 3 minutes w/ the ac and defroster on. It is always a relief to pass sniffers. Link to comment Share on other sites More sharing options...
csutke Posted April 29, 2008 Share Posted April 29, 2008 what do you mean both resonators? Link to comment Share on other sites More sharing options...
NismoSkyZ Posted April 29, 2008 Share Posted April 29, 2008 I think he means cats. Link to comment Share on other sites More sharing options...
chappy Posted May 2, 2008 Author Share Posted May 2, 2008 I guess they technically are front pipe assemblies according to Nissan. The cats attach to the manifolds then the front tubes attach to the cats. Its confusing because they look like a conventional cat with the O2 bung and everything, but all they do is dampen the exhaust note thats why I just call them resonators. The two shops that I got quotes from both called them cats as well, so I just gave them the part store item number to clarify. You can find some plenty of after market ones from bosal and the like.
