I know this has been talked about a lot, but when I typed o2 into search I got errors so here we go. It's about a 100 dollar part correct? and how easy is it to install? my car seems to be idling kind of rough and I was told this is what it is. I checked and cleaned my icv already and it was fine so it must be o2. also I have brand new bosch plugs.
yeah might be ur O2 sensors. You can get them at liek kragen for liek 80 if im nto mistaken.
Easy to replace if you knwo where it is. I dont know about your engine (i have an M20) btu it can be anywhere from below ur 6th cyclinger to near your tail pipe. Once you find it it is a simple job but may require a U-type tool to get to the other side. a simple plug from ur comp to ur xhaust managment.
