'92 350 that likes to stutter when you take off from a stop and when you accelerate when your passing someone. When i don't use the overdrive it runs allot better but still acts up once in a wile. I've replaced the fuel filter, cleaned the TBI, and replaced the O2 sensor witch seemed to work for about two days but then went back to her old ways so i threw another O2 sensor in and it didn't even do anything. I'm stuck and the code readers wouldn't even say their connected. Any help would be much appreciated.
