Weclome to NICO

The P01135 is coming from the o2 sensors being removed.

The P1110 is from the VTC solenoid, I'd check the connector and see if it's corroded or something because I don't think those fail real often...

the car feels like theres no power stumbles
i thought it was transmission but
i had codes come up as knock sensor and the vtc i took out the solenoids and cleaned the screens and sensor installed and then i used seafoam and changed oil
i read some guys change to a heavier oil and it goes away
my car has 180k miles

how many 02 sensor is there on the exhaust i found 2 on the catalytic converters and then if you go more down i found two plugs that are not connected anywhere wires cut looks like 02 sensor wires
