O2 sensors installed - bugger!
Tomorrow may be the first day of spring but I've got my spring tune-up and 100K maintenance done!
Had the dealer do the tranny service (I hate messing with fluids) but I changed out the O2 sensors and did a few other periodic maintenance items myself.
Read a number of posts on this forum regarding installation of new O2 sensors. Best advice I heeded was to hose them down with penetrating lubricant (PB Blaster stuff) LAST NIGHT before going to bed. That gave it about 8 hours to do it's thing. I got an early start this morning thinking I'd be a while getting those things loose (I'm 98% sure they were stock) but the penetrating lub made all the difference. It was cake getting them off. Unplugging the pre-cat sensor though was a PITA!!! Thankfully whoever engineered the plug made it so you press down to release the clip. I figured that out on the post-cat sensor first.
So, hopefully this post will help someone else in the future. I just have two sensors, on the passenger side. If you've got big hands, maybe see if you can bribe your kid or a neighbor with small hands to help you get the old pre-cat sensor unplugged and re-installed. That alone took me about 30 minutes total to contort myself and really busted up my knuckles getting the old out and the new in.
