Ever since I rebuilt my motor for my turbo kit I've had this code and the car has been running like dog **** (even if the check light isn't on). The car idles fine, just doesn't accellerate all that great. I know I have a loose valve but I don't think that's what's causing it. When I did a tune up the spark plugs were pitch black (#1 o2 sensor was too when I check it) and they had a white film on the tips.....what's that carbon????

61 Primary Oxygen Sensor....Where is this and Where is it located on the car?

Sorry to be so dumb but this is really getting on my nerves

 

thats the first oxygen sensor, located before the cat.try swapping it out for one that works, or buy a new one

 

is that the one on the downpipe? there's one on the cat to.

 

?

 

yep, the one on the dp

Hmmm....is there something I am missing here? You can rebuild your engine for your turbo kit but you don't know what an oxygen sensor is and where it is located?
