Throttle stuck at full acc - 1995 Chevrolet Corsica

Throttle stuck possibly

Kindly check the throttle. Maybe it could be stuck. You may spray WD40 and apply some lubricant on edge of throttle lever

John, first make sure it is not floor mat or carpet holding gas peddle down causing throttle issue. If all looks good there, would suggest you check throttle cable for being seized, throttle body seized or return spring faulty/broke. You may want to contact a good Tech, have them diagnose and estimate repair. Check the attached links,instruction and guides, Good luck

check for missing throttle return spring on the throttle lever

first you must disconnect the throttle body components, then take off throttle body. then you should have full acces to your intake manifold. you should also beable to see all the nuts or bolts that hold the intake manifold in place. unbolt them and take it off. keep in mind you are going to need to buy a new intake manifold gasket befor putting it back on. good luck

Disconnect the MAF sensor and see if it changes rpm's. Pull off the big boot at the intake. Is the throttle valve wide open? If it is, the throttle body assembly needs cleaning-maybe it is stuck?
Have you scanned for trouble codes?

Check that the floor mat isn't caught under the acc pedal,or the cable is fraded.take the cable off from the throttle and see if it moves freely,if not replace it.

You want the car to re-learn throttle after taking out battery?

FIRST ! check to make sure acc. pedal has full travel- like the floor mat or garbage doesn't obstruct it's travel.

Turn key to on, but don't start it.

Mash the pedal to the floor and hold it there for 10 seconds.

Release pedal and turn off key.

-you have just reset the "fuzzy logic"-

The throttle position sensor is most likely bad or it just may be the throttle cable but I think it is the Throttle position sensor it is located near the throttle valve follow the throttle cable to the end this is where the throttle valve is and the Throttle position sensor is located near the throttle valve on the opposite side it will have a plug going to it and it is held on with two torx head screws purchase the tools and replace.

check and see if choke is stuck shut or if it is stuck at least partially shut if it is fix the choke to work properly.
