89 5.0 runs fine cold until engine warms up after like 15 mins. CEL comes on and it starts sputtering and bucking on acceleration. Pull codes and get 41 and 91. So im going to replace my h-pipe with new cats and o2 sensors given they have 242xxx miles on them. My issue now is getting it to the exhaust shop to have it done. Can i just unplug my coolant temp sensor and get like 25 mins of operation so i avoid the 02 coming on when its warm and maybe get it to the shop without it bucking and backfiring?
