I dont know if it is normal or not but, it at rpms above 2500 the engine sounds rough. For whatever reason, when it rains the engine smooths out. A buddy has a 97 TJ Sport and he says his does the same. Is this normal? If not I was thinking it might be the belt.
Please explain your logic on this...

I don't know but am just asking, does an 04 Wrangler have downstream O2 sensors? I thought downstream sensors on Wranglers began in 2005?

I agree with others on NO Bosh sensors. I have seen them go bad within weeks of install.

My 02 TJ has both upstream and downstream, so I'd expect that an 04 would as well.
