Hey! I just changed the upper O2 sensors like you recommended and it seems that the rough idle is gone!!! OMG im crossing my fingers so it stays that way, you were absolutely right! I really appreciate your help and time, you da man!

Keep us updated. O2 sensors only have a usable life of around 75-100k. They are one of the most overlooked tune -up items after that is the fuel filter.

Yeah, my truck has 134k miles and O2 sensors looked stock. Ask me if I would ever change them again LOL . What a pain in the ****!!! Hated every part of it, at least on passenger side, other one was piece of cake

Fought with my passenger side when I changed mine a yr ago but realized afterwards that removing that tire makes it way more accessible especially for the plug. You can reach right in there. remove the splash guard too

Christiancito

Yeah, I squeezed my hand thru the splash guard to be able to grab the plug, that was the hard part. Removing the actual sensor from the cat wasn't terrible. Anyways, i hated every part of it. I rather change plugs and coils that do this again

Well, I think I got excited too soon about my truck's idling issue being gone. After driving it for a couple of days its back to what it was before. I disconnected the battery when i replaced the O2 sensors so im guessing that after the "idling relearn process" it went back to its old ways. Now I wonder what the real problem is

Grisha

Did you ever end up finding your problem?

Christiancito

I thought it was the O2 sensors, it worked great for a couple of days but not the issue is back, im guessing after the idle relearn process it went back to how it was before

Christiancito

Still dealing with this issue. Can't figure it out. It's driving me nuts. Only thing i haven't done is a compression test. Don't know if it's worth the pain

Anyone figured this out yet, running out of patience and money lol
