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 smile.gif.

/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.

Small update, after monitoring and clearing codes, cleaning and doing everything EXCEPT the catalytic converter, I bite the bullet and got a new Cat direct from Toyota parts.

Why you may ask? Why did I not take apart the cat and drill a small amount out? Why didn't I clear the code, drive it 50 miles, put 94 octane in the gas tank and then get it smogged?

Simple. It was throwing a p0420, and after examining it after taking it out (which by the way SpecialEdy is NOT as easy as you made it sound) it was just too far gone to be at all salvaged. Instead of trying to drill out the fraction of an inch myself with a dremel, I just bought a new one and hope to save my other Cat.

To quote a man I work with "Sometimes there's no way around it, you just have to bite the bullet and do it."

I will get it smogged and post results for future reference to any who have thrown these particular codes

p0133
p0420

/edit: also, in reference to the Berryman's regiment I referenced earlier, OMG it is amazing. Here is why
#1 No more sticky pedal
#2 It feels as though I have instant response at the throttle
#3 The sound of the engine is overall healthier (by which I mean it sounds a bit bassier and as if it runs smoother)
#4 This is probably placebo from spending money on upgrading numerous parts on her but, after the regiment she feels 100k younger.
#5 freeway entrances have a smooth acceleration, not sluggish or in a slight struggle to go the necessary speed in a quick distance
#6 It's just cool watching black gunk ooze out of the air intake

Thank you for your support, I appreciate this site greatly and hope this small contribution can help someone in the future.
