2nd photo was from the other day that’s my bad, the o2 code just comes up multiple times, gonna go to work and check it again when I get home and see what it says. Reason I posted both was because they say o2 but there 2 different codes?

Because they are 2 different faults with the #1 O2 sensor.
P0135 is the computer has detected a short in the circuit.
P0030 is the #1 O2 sensor is not doing its job. Probably because of the short circuit.

You ether have a bad #1 O2 sensor or a fried wire leading to it. The reason they seem to come and go is once the sensor heats up from exhaust gas it starts trying to work. The heater is only effective during warm up.

yeah currently that’s the only code I have is the p 0030. I’ve changed both camshaft selnoids(I know that’s probably not right) and I did the camshaft positioning sensor. Now that’s the only code I have left^ once again though not positive, going to run it tomorrow and see if more codes pop. Haven’t seen the misfire code in a week or 2

So I think the wiring throughout the car is burnt up, previous owner didn’t do much maintenance. With that being said though I just bought the O2 sensor so doing that when I get it in
