i have code 2342 which is the heated oxygen sensor code.. it comes on if i leave the car idling for a couple of minutes.. but i can get it to sometimes go away by driving for a lil bit..

i had a leaking power steering pump and the mechanic still didnt clean all the residual oil up and it still smells a lil bit.. could this be causing that sensor to display an error code?

i just dont want to spend the 100 bux if its something thats not a sensor

the car has 65k on it

94 100csq avant

thanx a lot
