Hello. I have a '91 Sunbird LE convertible with a 4 cylinder 2.0 liter OHC
motor that uses way too much fuel. I'm getting roughly 12 MPG! I have done a
few things in the course of trying to tune the vehicle up, as well as attempt
to fix the fuel consumption problem, and they include:
replaced the alternator
battery
spark plugs
starter
air filter
MAP sensor
Idle Air Control Valve in the throttle body
all seals in throttle body and cleaned well
The plugs keep fouling out, I can only assume, do to the excess fuel not
being used. Also, the engine seems to miss ever so slightly. Any suggestions,
however small or lame (lol), would be most appreciated! Thanks!

Sounds like way too much just for the O2 sensor.
However, its probably shot by now anyways.
I would suspect leaking injectors to be losing that much fuel.
The cat has got to be burned out, too.

there is a coolant temp sensor that tell computer temp of engine . get
one at auto parts so you know what it looks like and give it a try.
theres also a temp sensor that works the temp guage but dont get that
one. those 12 dollar manuals at auto zone will tell where the sensor
is.usually on the head near the raiator hose. lucas

hey i had the same problem i did a code test on computer and it was th
tps sensor which meters the fuel intake before i replace the tps senso
a hald tank of gas would get me about 40 km bad hey when i repalce th
tps sensor it got me over 250km on a 1/4 tank of gas so more the
likely it your tps sensor does you check engine light come on then of
again at certain rmp leve
