Multiple fault codes but no CEL

Clear and go after the first one that comes back.

Thanks for the reply.

I cleared all I thought, and everything came back. I might have a vacuum leak. will check tomorrow, and will keep you all posted.

Like the title said there’s some new faults after I did some things, but some remained. P0300, 0171, 0172, 0100, 0101, 0102, 0103, 011B, 0136, 0137, 0138, 0139, 0141, 0335, 0420, and 043E. Alright, so I checked for vacuum leaks by doing the carb cleaner trick, be careful with this as this fluid is flammable, but no vacuum leak detected even though I have the hose from the intake manifold to the evap purge valve deteriorated. See picture below. I replaced the evap purge valve, I think the old one is caked with carbon, meaning the canister is failing. Sigh, got to change that I guess. I bought the wrong sensor, cam position sensor, when I meant to buy the crank position sensor. I’d have to go return it, and don’t have time to mess with that right now. I’ll buy the O2 sensor while I’m at it and hope to install next weekend.

Alright, so I've done some research and I think I've narrowed down the culprits.
Just dropped about $220 US on both O2 sensors and MAF sensor. All Denso parts from RockAuto, I consider it cheap since they're all OEM. I didn't want to just replace one O2 sensor, since they work in tandem and I'm sure the other one is probably going to fail soon. She has over 140k miles, and I hope to put another 100K or so.
Also, I have an exhaust leak from my axle back, I've jerry rigged the muffler a couple of months ago, but it's not holding up. I convince my wife that I can't pass emissions with a leaky exhaust, so she let me drop about $300, including shipping, on a new muffler, I didn't tell that it's a Tanabe Medallion Touring-S exhaust. Hope they all get here before the weekend. I'll scower the junkyard this weekend or the next for an evap canister, that's just too expensive to buy brand new.

Here's the link to the site where I bought the muffler, it's the cheapest I've found: https://sparktecmotorsports.com/i-30...hback.html?v=1

Congrats on the Tanabe. Beautiful piece of hardware. I looked at them before I bought my Megan. I only bought the Megan because I found one on eBay for $100.00. The Megan narrowed to 1.14" where the tip attached to the muffler body - far too restrictive for my 2ZR turbo, but probably perfect for a stock car. Any chance you could do me a favour and measure the diameter at the tip and muffler body connection? Tanabe says 50mm ID, but I wonder if that's all the way through. Right now I have a Walker turbo muffler on there and it's only aluminized. Down the road, I'd like a nice, mandrel bent, SS solution.

Sure thing! The diagram shows it narrows at the neck of the tip though. But I'll take measurements anyway and picture of the inside of the neck. I'm hoping it's good enough for NA 2ZR when I finally get mine in.
I'm supposed to get all the parts on Friday. Looks like I have a small project to do this weekend.

All the parts on Friday for your o2 sensor/MAF work, or for your 2ZR swap?

Thanks for being willing to take the measurements. I bet it will come in handy for more folks considering the Tanabe.

Cheers,
