i had the cel come on last night and pulled the code and it was p0430. The scanner said bank 2. I am assuming the code is for the front o2 sensor by the radiator. I replaced the cat and y-pipe about a year ago, ut the pre-cats are original with 115,000 miles on them. Anybody had this?

IIRC, 430 is for a bad pre-cat(exhaust manifold catalyst). That gives you three options; new exhaust manifolds/pre-cats(major cash), headers(also major cash, but worth it) or gut the pre-cats and install mil-eliminators to prevents the CEL from not having pre-cats.
