1997 GMC Sierra issue
350,auto. Had a cat code come up ( bank 2 ) was told cats were bad, have replace but still could drive. It started bucking and stalling like no gas. Hubby punched holes in cats and still starts, drives 1/2 blick and stalls snd refuses to restart. Have not had a code since cat code was cleared. Any ideas?
