Will this help me figure it out by reading values or only help if I have a check engine light on?

I think you should just get rid of it, or fix it.

Get it tested. They will take an hour or so to run some tests and you'll be 150$ short so you know how low you should sell your car for.

I bought a scanner and will be running through https://youtu.be/RZ_DLBQN548 to see if it is indeed a misfire.

Just a follow up. I put some STP water remover in the gas and the issue is almost entirely gone. The car did sit for a couple weeks with some crazy temp swings so it may have just been condensation.

That's weird. It sounds like some kind of limp mode for sure.

Hey all!

Me again! Yep,,,, this saga continues. The issue returned and I got an odb2 scanner on the thing.

I get random cylinder misfires across all cylinders.

I checked the o2 sensors and sensor 1 bank 1 returns no data at all and sensor 1 bank 2 returns data I don't really know how to interpret.



Getting no data from Bank 1, does this suggest my O2 sensor is dead?

There is an upstream o2 sensor and a downstream o2 sensor.
I'm not sure if you should be able to read data from both, but if it was a bad o2, I'm pretty sure you would get a code. A bad o2 would also get you into limp mode, which would prevent engine to rev as well...

My ultragauge receive data from both so there is something odd for sure. But why you don't have a CEL is beyond me
