The other day, I was comin home, engine felt kinda jumpy, the it completly lost engine power and I pulled off the road and I popped the hood and the o2 sensor was glowing, and my runner wouldn't start again, I diagonsed the codes today and got 3, 6, and 10, then i turned it over to see if it would start, and it did, then I got codes 12 and 5 to add to the list, after it started runnin real crappy, I figured 5 would throw since it was glowing around the o3 sensor, but the other codes, im at a loss at what it might be! Any ideas?

Sounds to me like your catalytic converter is plugged up. That would cause the power lose and the glowing O2 sensor

I'm not sure about the codes though, If you don't have to worry about emissions try punching out your cat

Thanks for that, I was thinkin it mightve been the the cat, but it was so sudden, and I just took emissions for the last time required for it, I just don't know why the knock sensor code would throw after everything else, as far as codes 3 6 and 10; I think the ignition coil is bad

If you have an ohm meter, you can test your coil pretty easily. I don't remember the correct specs, but I bet a little googling would turn 'em up.

Well it started with codes still. But I wasn't up to running temp. If it was the coil, wouldn't it not run?

So I took the valve cover off to see if it was the timing chain, and nothings wrong there, any other ideas on what I could check?

No, it'll run even with a bad coil...just not well.

However, from the codes you're getting I'd put my money on ECU or O2 sensor, or both. And especially if it's glowing around the O2.

I'd spend some time googling each code separately, for example "22re code 12" and see what people are coming up with for symptoms/fixes.

Ok. I just bought an o2 sensor yesterday and was gunna swap it in tonight, well see what happens, ill keep info posted, thanks for the help so far

So it turned out that it was the o2 sensor! All codes are clearand she's bangin like a champ again. Its odd somethin so simple would do that!
