Smog failure, High NO, and what I am going to do about it Options

[HaysoosKreesto]

Well, I think I have found the problem through connecting with an old friend (old 6gc.net posts) but I guess I just wanted to post something recent for any other cali native who would suffer the same fate as I did! Embarrassing knowing you've taken good care of your girl and she fails smog.

None the less! I have learned a great deal that can help me preserve her and function more efficiently.

This is my smog test:


This is the code I pulled from her (sorry it isn't orientated upright):


From what I can gather I have these problems to fix:
#1) replace the upstream o2 sensor
#2) check to see if there are any vacuum leaks in the system
#3) clean the engine intake manifold and the tops of the pistons via chemical additives

This is more than likely what is the cause of the failed emissions, because on my previous smog reading (before I realized to use the more proper oil for her and to use higher quality gas) all of her emissions where basically just below the max, but they were all lowered after some TLC.

After some research, another cause of high emissions (although I don't believe this was the cause of mine, however, I am sure it contributed) would be a gunky engine. The buildup of sediments from thousands of miles of use w/o the aid of additives can cause a slowing of performance, and higher emissions because dirty particles are being thrown out of the tailpipe from the stockpile building up in your system!

I will be performing a Berryman regiment on her so she can be as squeeky clean as possible before I take her to get smogged again. At O'Reilly's (formerly Kragen) the 3 step professional fuel system maintenance cleaning kit is $33.85 + tax at the time of this posting, which shockingly is cheaper than Amazon!

If you didn't know, she is a 1998 Toyota Celica GT 2.2L Automatic and her name is Delilah .

/edit: Question: Should I wait on doing the Berryman's until I have to change the oil again? She just got an oil change about 500-1000 miles ago.

Here's a good resource page for you: http://www.aircare.ca/repinfo-ere-causes-nox.php

Ehh, as far as fuel system cleaners etc... You'd be better off changing the filter and taking the injectors off and having them flushed and rebuilt if needed. I'm not sure on the 5S, but on my 7A it was fairly easy to remove the fuel rail.
