Yep, autozone did it. However, different codes from autozone and tccoa

In Autozone it came back with p0420 and p1505

02 sensor and IAC

however, it didnt specify which 02 sensor.

i looked up these codes online at tccoa - http://www.tccoa.com/articles/misc/index.html#

completely diff #'s.

bump

bizzump

What year is your car? 89-93 will have a 2 digit code and 94-97 will have a three digit. Not sure what type of scanner autozone is using.

94 thunderbird, not lx - 4.6l v8

that is an LX, but that's besides the point.

seems those are the OBDII codes.
