which oxygen sensor is which??
also posted in engines.....
To make a long story short, i took my pickup to autozone, and they told me that i needed two new oxygen sensors, "number one and number two" they sent me the before and after cat version. now i don't know which side they go on, i tried to tell them there was 4 of them, and they said there were only two. so.. which two are one and two, the left side or the right side?? thanks in advance.
