I have 3 issues:

Just got a p2098 last night. My new cats and sensors were installed in August 2021. Could it really be the rear O2 sensors bad?

My current mods are JBA headers, new walker OEM cats, mid muffler delete, 180 tstat ,and a JLT intake. I currently run the 93 tune. Is this the correct tune for my set up.

For the 180 tstat, what should I set my fan too in the Diablo sport i3 tuner?

For the 180 tstat, what should I set my fan too...?

188* & 198* It starts to open at 180 and takes 15-20 degrees to be full open. Those numbers are a good starting point. Adjust as needed to find your sweet spot.

At least on the gen-1's, there's only low & high. The i3 provide a mid speed setting, but IIRC it got set to match HS.

How do you like the hotchkis suspension?
