Thanks for choosing FixYa and welcome. Your EGR valve may be bad or it may need cleaned. If it is stopped up, it will cause stalling when the gas is pressed. You may also want to check the fuel filter/air filter just in case. Check for any vacuum leaks as well. Being that it is an 90 model, clean the EGR and valve first. If you have a check engine light on, get the codes off of your computer by taking it to Autozone or Advanced.

Check all vacuum hoses.

Hello, My name is Mike. First of all I do not know everything, but I am a certified mechanic and expert trouble shooter. That is what I do. This especially comes in handy with helping customers like you solving issues with there car with out me seeing it in person and using my computer and other testing methods to dissect it down to the root of the problem. But based on your good description and from my years of experience here is what your problem is.

The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. When this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue. Sometimes another area which will sometimes contribute to this issue is the 02 sensor, but based on your symptom, I believe the torque converter clutch solenoid is the area that needs replacing and of course at same time transmission filter and replacing fluid would solve this problem. I hope this helped you. Mike

You will need a vacuum tool to test the movement of the EGR valve.

A stuck / no closing EGR will cause the car misfire.

=====
Check / clean air filter

Check for oil on plus

Change PCV valve

First find out if you're missing spark or fuel. Then get back and we can go from there.

an auto parts cud help you--they would havit on computer and help put in on

their is no reset button for the fuel pump on a 1990 olds. their is a relay located under the hood though but these rarely go bad.. might be worth a shot though

you cant if thay are not laying down when turn engine off or stuck in the air then you need to replace the motor as the trans in wiper has jumped and their is no reseting it.

hose or inlet on intake is stoped up building up presure in the engine

Hi,

Thank you for contacting fixya.com.

Check all of your vacuum lines for cracking and dry-rot or bad EGR valve. So vacuum leak can be a reason .Also check thoroughly the fuel pump, fuel pump relay and the fuel filter. If you get fuel to the injectors then it's the ECU that is bad.

Please check this link to have a detailed idea to troubleshoot your problem related to your query:-

Please get back to us if you have further query else please accept the suggestion.

Check the alternator with the belt off and see if you can move the pulley freely.Sometimes these alternators will lock up because of bearing failure and when it does the engine is not able to turn over.

Yes please put forward your problem so that i will give my best to fix it up.

it would be easy to test the catalytic converter, just remove the O2 sensor and see if the engine will run if so replace the converter, you did not list what engine so i cant really give you any advice on what to look for get back with me with the engine size and what fuel system and i will see what i can do for you.

Check for spark. My guess would be the ignition module going out, but could also be the crank sensor. The module sits under the coils. Check all coils for spark. If any coil doesn't spark, you can try replacing just that coil, but the problem may still be the module underneath. If you have a meter, run a resistance check on each coil from the terminals to ground. If the same coil that doesn't fire aslo has a different resistance, replace that coil.
If you have a meter, check the AC voltage on each of the crank sensor wires shown as compared to ground or battery positive. If the AC voltages are different on the three wires, suspect the sensor is bad, but also check the tone ring on the pulley (Fig 2 below) for any damage.
Please see my tip at http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines for how to check for spark. These are genericinstructions.
The 3.3L engine is the only one with the C 3 I system. REMOVAL and INSTALLATION C3I Module See Figure 1

1. Disconnect the negative battery cable.
2. Unplug the 14-way connector at the ignition module.

Fig. Fig. 1: Distributorless C 3 I coils and module system - 3.3L engine

1. Tag and disconnect the spark plug wires at the coil assembly.
2. Remove the nuts and washers securing the C 3 I module assembly to the bracket.
3. Remove the 6 bolts attaching the coil assemblies to the ignition module.

To install:

1. Install the coil assemblies to the ignition module and install the 6 attaching bolts.
2. Install the nuts and washers attaching the assembly to the bracket.
3. Connect the spark plug wires.
4. Engage the 14-way connector to the module.
5. Connect the negative battery cable, then reset the clock, radio and any other accessories.

Ignition Coil(s)

1. Disconnect the negative battery cable.
2. Tag and disconnect the spark plug wires.
3. Remove ignition coil attaching bolts, then the ignition coil from the module.

To install:

1. Install the coil(s) and attaching bolts.
2. Connect the spark plug wires.
3. Connect the negative battery cable, then reset the clock, radio and any other accessories.

Dual Crankshaft Sensor
See Figures 2, 3 and 4

1. Disconnect battery negative cable.
2. Remove serpentine belt from crankshaft pulley.
3. Raise and safely support the vehicle.
4. Remove right front tire and wheel assembly, then the inner access cover.
5. Remove crankshaft harmonic balancer retaining bolt and crankshaft harmonic balancer.

Fig. Fig. 2: Harmonic balancer with interrupter rings on C 3 I system

1. Unplug the electrical connector from the sensor and remove the crankshaft sensor from the vehicle.

To install:

1. Loosely install the crankshaft sensor on the pedestal.

Fig. Fig. 3: Dual crankshaft sensor - C 3 I system

1. Position the sensor with the pedestal attached on special tool J-37089.
2. Position the tool on the crankshaft.
3. Install the bolts to hold the pedestal to the block face. Tighten to 14-28 ft. lbs. (20-40 Nm).
4. Tighten the pedestal pinch bolt to 30-35 inch lbs. (3-4 Nm).
5. Remove special tool J-37089.
6. Place special tool J-37089 on the harmonic balancer and turn. If any vane of the harmonic balancer touches the tool, replace the balancer assembly.

A clearance of 0.025 inch is required on either side of the interrupter ring. Be certain to obtain the correct clearance. Failure to do so will damage the sensor. A misadjusted sensor of bent interrupter ring could cause rubbing of the sensor, resulting in potential driveability problems, such as rough idle, poor performance, or a no start condition.

1. Install the balancer on the crankshaft and install the crankshaft balancer bolt. Tighten to 200-239 ft. lbs. (270-325 Nm).
2. Install the inner fender shield.
3. Install the tire and wheel assembly. Tighten to 100 ft. lbs. (140 Nm).
4. Lower the vehicle.
5. Install the serpentine belt.
6. Connect the negative battery cable, then reset the clock, radio and any other accessories.
