So I'm driving home from work going up a slight hill and instantly have almost a complete loss of power. The CEL was blinking and I managed to limp the truck home, to be towed tomorrow. I checked for codes and there are none being shown. The truck is running very rough and seems like it's gonna stall any minute. I'm just guessing it's either the cat or injectors or both. The truck has 325K and both the cat and injectors are original. I just replaced all coil packs so I'm thinking it's not them. There is no sulfur smell just running rough. Can anybody tell me the different signs of a bad cat vs a bad injector. I love this truck and just put a bunch of time and sweat into replacing a charcoal canister and I'm hoping this may be something I can fix myself. Thanks everyone for all your help over these flyby years.
