Why does your 1996 corsica 3.1 idle super high replaced throttle pos sensor still does it has great vacuum?

It wouldn't make much of a vacuum leak to cause the engine to idle at high RPM. First check for vacuum leaks even though you may still have good manifold vacuum.

What is wrong with a 94 ford ranger jerking - replaced mass air flow sensor and throttle position sensor?
vacuum leak
1999 Saturn sL1 idles high?
throttle posistion sensor or vacuum leak
Why would an 2002 impala sputter when in idol mode?
could be a vacuum leak, or throttle positioning sensor
Where is the map sensor located on a 1995 Chevy 350 throttle body?
Passenger side of engine next to throttle body. It is the senor with the vacuum line running to it.
Where does a 87 Chevy 305 map sensor vacuum line connect?
on the back of the throttle body or intake port.
What would cause your 94 Mercury Tracer to idle rough and stall when stopped at a light We have already replace the Mass Air Flow Sensor and the Exhaust GAs Oxygen Sensor.?
Look for a vacuum leak. With the engine idling, anywhere you have a vacuum hose attached, Spray some throttle body cleaner at the connections and see if the engine idle picks up even just a bit. If it does, you have a vacuum leak. After checking if you do not find anything, at least spray some throttle body cleaner in the throttle body and clean the throttle blade up. Also try the Idle air Control Valve Located on top of your throttle body, or even the throttle position sensor
1997 Suburban low speed miss?
vacuum leak,plugs or plugwires,fuel filter,throttle positioning sensor,
Where is the map sensor located in 2000 Toyota Corolla?
its mounted on the fire wall with a vacuum hose coming from the throttle body to it
Why is the idle speed on my 1997 T-100 too high?
Throttle position sensor bad, throttle butterfly stuck, severe vacuum leak. Check those three things.
What cause of early shifting of automatic transmission?
A sensor has failed, and is reporting the wrong value to the transmission controller. Old transmissions: Probably the vacuum modulator or throttle position sensor. Also check the fluid level. New Transmissions: Output speed sensor, turbine speed sensor, throttle-position sensor, fluid pressure sensor, and sensors on the engine.
What sensor would cause engine to run at very low idle and often die?
If it's a sensor, it will usually be the TPS aka Throttle positioning Sensor, but most of the time it would be a Vacuum leak
What does an automotive Map Sensors do?
A MAP sensor is an anacronym for "Manifold Absolute Pressure" sensor. The sensor has a vacuum line going to it from an intake manifold vacuum port. It senses the amount of intake manifold vacuum or pressure depending on how far open the throttle (your foot) is when you drive. Wide open throttle-foot to the floor, dictates low vacuum in the intake manifold. This device is all part of your engine electronic control devices/sensors used to make your engine run at peak efficiency and perform its best.
