This sounds like a bad vacuum leak but you will need to get the codes for the engine light first, these codes will tell you what is bad as far as a sensor and this is very hepful, it may be a bad mass air flow sensor too. there will be codes, the computer stores codes and turns eng light on when it sees a problem, i would send you to an auto part store to scan it for free but this car is to old, you will need to go to a shop or scan it your self, doing it yourself gets confusing, you will need to count light flashes and then turn into numbers and then turn the numbers into definitions of the code,

Hello: Look under the car and you should see the fuel filter. You DO NOT have to remove the fuel pump if your car is a 1988.

Hi, you may be looking at the cruise control release switch. The stop light switch is behind the pedal as shown below. You're right--this is not an easy fix. After replacing, you need to make up a special tool to adjust it.

1. Disconnect the negative battery cable.
2. Remove the three fasteners from the left side insulator panel.
3. Slide the steering shaft protective cover towards the cowl.
4. Remove the vacuum hose at the cruise control cut OFF switch, if so equipped.
5. Remove the stoplamp switch-to-steering column bracket retaining pin.
6. Unplug the electrical connector.
7. Push the switch arm to the left and towards the cowl to disconnect switch-to-pedal arm. Release the snap clip and remove the switch.

To install:

1. Install the switch and push up until it is seated into the top snap clip.
2. Attach the electrical connectors.
3. Connect the switch to the pedal.
4. Install the switch-to-steering column retaining pin.
5. Connect the vacuum hose if equipped with cruise control.
6. Install the steering shaft protective sleeve.
7. Adjust the stoplamp switch.
8. Install the left sound insulator, connect the negative battery cable and check switch operation.

ADJUSTMENT

1. Depress the brake pedal (push down), as far as possible and hold.
2. Using a stiff wire with a hooked end, gently pull the switch set lever forward (toward the front of the vehicle), and listen for an audible click that indicates release of the automatic adjuster.

If no click is heard, release the brake pedal and repeat the above procedure.

1. After release of the automatic adjuster, slowly pull the brake pedal all the way rearward. Listen for the switch to ratchet into the set position (setting the brake light switch). At least three clicks of the ratchet should be heard.
2. Inspect the operation of the brake lights, as follows:
   1. The brake lights should light at maximum brake pedal travel of 1 1 / 4 in. (32mm) and throughout the remainder of the pedal travel.
   2. If the brake lights do not light, repeat the switch adjuster procedure one more time.

the brake switch is directly above your brake petal, look at the brake petal bracket, the switch is attached to it.

Just did one in my shop yesterday. MY problem was injectors shorting out drivers in PCM after half hour of cooling down it would restart and die again about 20mins later. You need to narrow down what is dropping out. Most likely your loosing injector pulse and/or spark. You can buy a noid light for injector testing and a inline spark tester which you can tag on igition coil pack from local parts store also you can tag into injector harness on passenger side of engine with noid light, when it stalls see if light is blinking while cranking on both testers. IF you have spark but no injector pulse you have one or more injectors shorting (acceptable range is 13 ohms) any lower than 13 ohms injectors are toast. IF no spark and no pulse your ignition module and or crank sensor are bad, replace both, module is under coil pack and sensor on side of block.

On your engine...guessing you have the 2.8L, find your tensioner and put a socket and ratchet or breaker bar on it and rotate it a little or as much as you need to slip the belt back on. It should look like this:

ck fuzes brake lite switch shood have power on one side mash brakes shood be other side

The most likely cause of this would be the switch, check that the terminals behind the switch have come loose and are touching, Or else the contacts inside the switch have weakened or broken and are shorting - replace the switch. As a trial, disconnect the wires and insulate them for a while to see if the fault re-occurs.

Your computer should be under the passenger side of the dash, behind the glove compartment, or inside the right side kick panel.

You probably have a short somewhere. You need to check the wires and make sure they all have voltage. Check your fuse as well first.

It should be under the car on driver's side. It will tucked up inside the frame about midway between fron and back.

check fuel pump fuse and relay if they check out good replace pump

Not difficult, but belts rarely just shred for no reason, check all the pulleys that the belt goes on.
