Where is the map sensor located

If the idle air control valve is bad, you'll have trouble with rough idle, stalling, surging etc. along with the sluggishness. The Mass Air Flow sensor is more likely the cause. Not sure where you're located but at AutoZone, you can return the part if you have to.

All the above problems were happening to my truck, and the engine light never did come on. Finally changed the O2 sensor, and it runs like new again.

Hello! The problem is more than likely being caused by the Manifold Absolute Pressure (MAP) sensor...It is bolted to the side of the throttle body...Has wire colors Gray (+5volts)...Light Green (Signal out)...And Black (Return or Ground)...Using safety pins...Push the point into the rear of the in-place MAP connector...Clip the (+) meter probe, set to read +5volts, to the Light Green wire...The (-) probe to the Black...Start the engine...At idle reading is close to +5 volts...At 2500 rpm reading drops to 1.5-2.0 volts...If you have already replaced the MAP and do not get these results...Pull the MAP connector and read back into it using the same procedure...If, for instance, the Light Green signal lead remains on +5 volts it is probably shorted to the Gray in the harness...No voltage is present; The Gray wire is open...Or, No ground on the Black, the Black is open...Whatever you find wrong...Merely cut out the bad wire and re-connect on both ends..See diagram of MAP location below....Send a comment via e-mail....Guru...Saailer

Your knock sensor is the probable cause. When the knock sensor starts to malfunction, it can cause sluggish performance especially when the car is under a load (such as going up a hill). This is caused by the knock sensor constantly retarding the timing. Hope this helps.

the MAP sensor ( manifold absolute pressure ) the sensor monitors the engine vacuum, as the vacuum decreases like when you accelerate or are pulling a load like climbing a large hill. the on-board computer uses this info. and other info. from other sensors like the TPS and MASS to make adjustments to the fuel mixture and ignition timing to give you the most power and fuel economy. the computer will use other info. if it thinks the MAP is not giving correct readings but with out this sensor the fuel mileage and power will be reduced, you need to have it repaired soon, it most likely will not cause the car to stop running but it will not run properly with out the sensor. also the car will not pass a state emission test with the light on and the sensor not working.

Discribe sluggish. Changing the fluid has nothing to do with shift stratagy or correct trans operation. Change the filter every time you do the fluid,unless your just pulling the plug every year or so,to change some fluid.
These vehicles have a tendency to have a bad Trans Solenoid Pack. If it bangs into reverse or shifts funny around 35 to 40 on a slight hill,that part may be going bad.
You need a proper working EGR Valve and TPS (Throttle Position Sensor) also.
Don't forget to flush the Power Steering Fluid--although unrelated to the trans.

Trans--Mercon V Fluid
Steering--Mercon (Not V)

I would first check the map sensor. If that is good, I would check the tps. There are test procedures at the link below. You will need an ohmmeter to test the sensors. A vacuum pump is not necessary. Just use your lungs to pull a vacuum on the map sensor just to verify it is working. Repair Guides Electronic Engine Controls Camshaft Position Sensor AutoZone...

Did the light stay on after the car was shut off and restarted?

I don't have the info with me as I am home, but to the best of my memory, Subaru uses a pressure sensor (MAP sensor) to measure egr operation. It is located on the right strut tower. I'm not sure but it may only be the manual transmission models that have one. However, if your vehicle does have one, the problem is NOT with the sensor but in the filter located in the vacuum line between the manifold and the solenoid (for the sensor). I have seen several of these that are only somewhat restricted yet it diminishes the signal to the PCM enough to cause a code to set.

Hi there, sounds like this car might have either a bad coil pack or the distributor cap has gone bad. 3 most important things are air, fuel and 12v power. Seems your getting all three but one of them is giving you trouble. Sounds like spark. Try a new distributor cap or a new set of coils and see if that solves the problem.

if it isnt the spark it has to be fuel or air which would lead to lack of fuel pressure which can cause sluggish behavior or the air sensor in the intake if there is any is not working properly and the computer is running on a safety fuel map that is a base map used by manufacturers which burns alot of fuel but stops the engine from destroying it self. Check the coils o the sensors.
