I replaced my Left (Drivers side) O2 sensor today. (Engine code 37).
I am either having trouble clearing the codes, or it wasn't the O2 causing the problem. (Still getting code 37).

Any ideas?

(I used the code clearing procedure outlined VKYKAM in another post:

To clear codes:

1) With engine off, stick the blue wires to 1st and 2nd pin in the top row counting from left on the black connector, with notch facing up.
2) Start car. Shut off car. Remove pins.
3) Read codes to make sure they are clear. No codes = steady blinks at 1/4 second intervals.)
