PO175 System too rich (Bank 2)???

On my 98, 5.4...I had 2 bad cop's. I replaced all the cop's and installed Autolight P plugs at the same time. Now the truck runs rough, has no excelleration...its a real dog now. Plugged into it with my scan tool when returned from the test drive and I get PO175 System too rich (Bank 2). The only thing I did different was to fill up with 91 octane gas instead of the 89 ethenol I always ran. Now Im lost again. Any ideas or anything of help? I really miss much truck...

they are the ones before the cat i believe ... located in the exhaust. they arent too much fun to change but definately i would do them your self and save the money. its a simple process just hard to get to. i just but the truck on jack stands and used a 22mm stuby wrench.. the connectors are behind the eninge block.. cant see them really so just go by feel. its a good idea to use pb blaster or some kind of penetrating lube on them to loosen them up.. may want ur exhaust hot also.

Would a bad EGR cause a rich fuel problem? Mine makes noises.

You need to start looking for stuck injectors or another misfire.
