RPO mismatches...maybe? Its fun to look up RPO's
 
C61 - hvac system,airconditoner, front aut controls
^ does that mean im supposed to have suto controls or am i reading that wrong

C78 - lamp,interior,roof,courtesy and single reading
^says i have one reading lamp when i have two?

Or am i jsut confused?

(WOOT i have F17 .. Final drive 2.84... i think, unless it like on of the above codes)

Im still only getting 15-20 MPG (maybe that because i think my bonne is supposed to be faster than it is so all the fuel goes into my accelerator foot that has to do a litle more work because my acceleration is so slow) But seriously i really need to look into the horrible gas milage/

Yep, 2.84 is what you have. Can you peel tires? My old 93' 88 cannot. It has issues that my dad has to deal with now. :lol:

If i turn enough to lighten up one side i can, or if its wet... otherwise it just bogs a bit and keeps pullin and pullin!

Yep thats the 2.84. Do you have a tachometer? Take it on a 400 mile trip. You'll get 30+ mpg. :D

If your as mileage is that poor and you're getting poor performance, it sounds like it's time for a full tune-up (including O2 sensor).

Thats the problem... i took it on a 1200 mile trip (600 each way) and i got mostly 22mpg (best ive gotten in forever... i think i need a new O2... i replaced plugs and wires not too long ago but they should proly be checked...
