Car cuts off when step on gas
91 oldsmobile cutlass supreme 3.1 liter.
Started cuttin off at stops but would restart
no issue. Then it would cut off an crank
right back up but if gass pedal touched it
would cut off. Now it won't crank unless i
spray throttle spray into it , will run about a
min then shut off. If gas pedal is touched it
cuts off instantly. Fuel filter, fuel pump,
throttle body sensor, plugs an wires, an a
few othwr things have been replaced, didn't
help one bit. Been messing with this for 2
Try removing the catalytic converter. It may be plugged. The car is old enough you can probably run it without one if you don't feel like replacing it.
That was the 1st thing i did. If i spray throttle body cleaner in it, it runs about a minute. I turned ignition switch on then depressed the , bleeder valve an gas squirts out like it should. I'm stumped
