hey guys i tried the mechanical o2 sim diy today... having some trouble drilling though the non fouler, i didnt drill it all the way but i as wondering if it would fit so tried to test fit the non fouler on my o2 sensor but it wont budge. it moves maybe like 90 degrees in both directions but aside from that its not going anywhere.... i tried wd40 and all the chemicals in my arsenal and nothin worked. i cant get this hoe off.... are o2 sensors reverse treaded?

uhmmm. I haven't had to remove my o2 sensors before but someone told me that you have to heat them up to get them to pull loose.
I hope someone else can verify this.

there is a special tool to remove it

my o2 sensor was a piece of cake to remove. you need a crows foot or o2 sensor socket to remove it, 21mm i believe. sounds like yours is cross threaded. if i remember correctly, i was pushing the wrench counter clockwise to remove it.

*im talking about the primary sensor, not the one near the cat.
