There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Light came on immediately? Well, sometimes folks electrically unplug or even remove the purge valve thinking that they don't need it anymore. Unfortunately, when the ECM doesn't electrically see a purge valve, it triggers a code and lights your CEL. If that's the case, just plug it back in. And I trust that you plugged the rubber hose that the purge valve is in that leads back to the engine. That should have been shown in the video.
Otherwise, start up the machine at idle so that the CEL is on. Call up the trouble code by simultaneously depressing the Mode, Set, and Turn Signal Cancel buttons. (turn signal button pushed straight in). A code will appear on the display. Go to this link and look it up.

You can come back here and post what it is and also do a forum search for the code. Probably isn't the first time it's ever happened.

That is an O2 Sensor Malfunction code. The one before the cat. on bank one. Sounds unrelated to me unless you inadvertently disconnected something or did not get a good seal on the PCV valve. Bank 1 is the right side. So, in the vicinity of the Evap canister you removed. Check your O2 sensor connections.
It could also be that the surging was not canister related. Did removing the canister resolve that issue?
Also, you might want to check the 2 vacuum lines on your throttle body. If they are leaking, they could be the reason for not only the original surging. But the code now being thrown.
Lastly, the 02 sensors do go out. So, it may be nothing more than coincidence. A bit unlikely, but at least remotely possible.

Minor correction. That engine is a 998. Bank 1 is the FRONT cylinder. That O2 sensor is accessed from the left hand side. It’s on the header pipe just a little way past where it bends and starts turning to the rear. P0130 means it is out of range too high or low. Check the harness connector on the left side, those two vacuum lines, and if this is a SM-5 transmission, check clutch assist vacuum line. That is in the vicinity of where you were working.
Otherwise, yes they do fail. If it comes down to it, replace it.

Could you post a link to that video? I have no luck trying to find it.

Didn't really see any problems with it....except that his background music interfered with his narration. But anyway, on the 998, the purge valve line goes to the rear cylinder of the motor - which is Bank 2. And you have a Bank 1 O2 sensor code. Maybe not related to that job specifically, but something else that buggered up the front cylinder O2 sensor or air-fuel combustion operation. As you are already doing, go back and review your work. You can ride it around for a few miles to see if the CEL and code clears, and we gave you things to check on and replace in case it doesn't, such as the vacuum lines, etc. I'd replace them just out of principle, anyway.
It never hurts to make sure that your other maintenance items are up to date. If it still has the stock plugs and wires on it, remember that they are 10 years old. The OEM wires were junk, anyway. Ron can attest to that. And run some injector cleaner, such as Seafoam, through it on occasion. Make use of the forum search function. You might find a nugget in here someplace. Good Luck.
