plugs and wires are not gonna stop you from running rich… :slap: you need to soak a rag in diesel fuel, stuff it in your gas filler neck, and then light it on fire. That will fix your rich condition in no time… ---

not sure how your car works but try unplugging the O2 sensor in your downpipe… see if the problem stays the same. ---

1. lay off the gas - hard to do 😃 2. get new plugs - expensive but i need too 3. get 4 new o2’s :eek: - this one might kill me 4. exuast leak - dunno 5. run premium ( not hillbilly backwoods 87 89 🙂 ) only run 93… did find out my parents ran 87 one tank when they borrowed it :mad: 6. shave your mullet ( good for 2-3Mpg ) - ill think about it 7. clogged cat or Cats ( i thought you removed them ) :dunno: - i have 2 left 8. Gas gauge off - sticks towards the top btu dunno 9. Its a Ford disregard everthing: your motor shit itself :eek: :)- that would be my luck ---
