Great video. I just found out I need a 02 oxygen sensor and I can’t find anyone to do it for me. So looks like I am going to do it myself. This video looks pretty easy to follow. Are these sensors sold separately?

[@Ghost_Automotive_DIY]

Thank you! If you go to an auto parts store they’ll sell it to you separately but if you look on line you should be able to find bundles.

@@Ghost_Automotive_DIY Ok. Thank you so much

@@mck8621 Anytime! Thank you for watching the video and I hope it helps!

[@mck8621]

@@Ghost_Automotive_DIY It helped a lot. I thought it was hard but I see I can do if I just take my time. Do you happen to know a website I can order them from and get them tomorrow?

[@Ghost_Automotive_DIY]

@@mck8621 definitely take you’re time and it’ll be done in no time. The only site that I know of was Amazon that does stuff like that but not sure if they have that option with the O2 sensors. I picked up the ones I used from an auto parts store
