Help with a few kinda technical issues. 02 sensor issues.

[BruhBrahBrad]

so lately I've been getting REALLY SHITTY gas mileage, so today I took the car to school, ran codes and checked the sensors. I suspected the 02's being the problem.

So here are my results of testing the 02's. r

Ho2s bank1 was lean and the voltage was EVERYWHERE anywhere from -130+volts to +130 volts... Im suspecting this being the issue.
Ho2s bank 2 was rich with a much more realistic reading of .0 to .90 volts.

No codes were givin when I did the test, Could this condemn the bank 1 o2 as being bad?

Also checked the tps voltage and it was 1.01 is that A good setting for it, I tried to adjust the screws but the IAC was in the way, and I didnt have time to remove it.

swap the o2's and see if the bad reading transfers to the other bank.
you might also have bad cats

its a catted x pipe, with the cats gutted, but they are after the o2s.

 

[BruhBrahBrad]

im gonna try that with switching them.

+130 volts??? in a 12v system?

gutted cats. you failed to mention that. lol

 

[BruhBrahBrad]

Yeah but the o2 is before the cats, which means it shouldnt be reading that correct? One side is fine, the other is fubared.

+130 volts??? in a 12v system?

I dnt think its actually that many volts but that the sensor is not giving/getting a proper signal, so the scan tools datastream was acting funky.

IF you had cats and IF they were clogged. That could be giving you the high fuel consumption issues as well as the bad o2's.
you might even have problems with the egr too.

Hmmmm so im not sure what you're getting at, since I dont have cats. You're right though, I should change my egr, this one looks stuck open at idle.
