[QUOTE="David Schmidt, post: 911494, member: 57602"] interesting...I replaced the oxygen sensors - upstream - two of them with Bosch with OE connectors, etc. Not motorcrafts but I'm told Bosch makes a great sensor. They seemed to work fine. I did not replace the one after the CAT. The web sites say their are "two" but I could only see the one after the CAT. I was told that one won't affect much - the two upstream are far more important. I'm hoping the left original oxygen sensor was bad but not throwing a code. I will monitor the plugs and get a factory IAC in the very near future and get rid of the Advanced Auto part one - at least the connector was pointing the right direction. Should I get a after cat oxygen sensor? [/QUOTE]
