Sounds like you're on the right track. A bad TPS and ISC motor sensor
will cause the problems you're experiencing. Your ECM relies on the
readings it gets from the TPS to be sure there is enough air getting to
the engine. If the ECM gets a bad reading and thinks not enough air is
getting to the engine, it will cut the fuel supply, hence causing your
engine to die. Your ISC relies on the reading from the TPS as well.
It detects from the ECM if the throttle plate is closed or not. If
it thinks the throttle plate is fully closed, it will start allowing
air to enter the engine and bypass the throttle plate. If your ECM
starts seeing some unmeasured air coming from ISC and detects the
throttle plate is open (which it may not be due to a bad TPS reading),
the ECM will again cut the fuel supply to avoid the risk of detonation.
So, replace your TPS first and see if that cures your problem. Also,
check the resistence readings of your ISC to be sure that is within
spec. If your problem still occurs, check your Intake Air Temperature
(IAT) sensor in your air filter housing. Be sure your spark plugs,
plug wires, and distributor are all in good shape as well. Replace
your fuel filter if you haven't done so in the past 2-3 years.
Good luck!
SOURCE: How to take out dash
I agree with 'jthall1', it is a major pain! Undo every bolt and screw visible to the eye. Then you have to find the ones that you can't easily see! (They are near the defroster vents and under the dash and also behind the glovebox.) Now that you have it lose and it still won't come down for you, you have to remove the, i believe its 2, bolts holding you steering column up. At this point you can now pull the dash down and gain access to the heater core, which you will probably have to ***pry*** off the firewall. As previously stated, IT IS A PAIN!!!!!!!!!! PS- Don't forget to take the lines and bolts off the heater core from under the hood!
SOURCE: cabin air filter
Tools needed are a Phillips screwdriver. Open the hood. Notice the cover for the cabin filter is on the cowl on the passenger side. Remove the screw form the cover.
Remove the cover by pulling toward the front of the vehicle. The filter is now visible. Remove by pushing up on the filter to loosen from housing and then pulling out toward the front of the vehicle.
Replace with clean cabin filter. Replace cover by lining up the notches on either side of the cover plate to the grooves in the filter housing. Replace the screw in the cover plate.
Good luck and hope this helps.
