My service engine lights are not on, but my car keeps cutting off. I have replaced the fast intake censor & the map censor and no one seems to know what the problem is. Can you help. I'm told these makes of vehicles are nothing but problems.
The vihicle randomly stops running whether it be in idle in Park or driving down th road. We have replace the Alternator, Ignition module. Still looking for problem...The vihicle randomly stops running whether it be in idle in Park or driving down th road. We have replace the Alternator, Ignition module. Still looking for problem...

I had the same problem and it turned out to be the wiring harness in the steering column. Found this out after replaceing the computer brain ($700) and various other parts. It seems it had a short and when you turn the steering wheel just right it connects and shuts the car off.

This problem is often caused by a failed MAP sensor. Is your engine light on? If yes, have the computer scanned. If the scan indicates a fault with the MAP sensor, replace the sensor. If not or not engine light, you can run some tests on the sensor using a volt/ohmmeter.
Here is a procedure I found at autozone.com:
Manifold Absolute Pressure Sensor
Fig. MAP Sensor power input testing-2.0L (3S-FE) VIN P
Turn the ignition switch to LOCK.
Reconnect the MAP sensor connector.
Turn the ignition switch ON.
Disconnect the vacuum hose on the air intake chamber
Connect a voltmeter to terminals PIM and E2 of the ECM, and measure the output voltage under ambient atmospheric pressure.

Apply vacuum to the MAP sensor in 13.3 kPa (100 mmHg, 3.94 in.Hg) segments to 66.7 kPa (500 mmHg, 19.69 in.Hg). (my personal note here: you can just leave the vacuum line connected to the engine and start the engine to apply vacuum.)
Measure the voltage drop from step above for each segment.
If operation is not as specified, replace the MAP sensor.
Reconnect the vacuum hose to the air intake chamber.
First inspect the boot from sensor to the intake manifold for cracks,inspect all the vacuum hoses to the intake.
second unplug the connector and inspect the terminal.Sometimes the plastic is burn and the wire pusht out of terminal. insert the wire all the way in or replace the pigtail.
plug scanner and monitor the air flow and air temperature on live data.
inspect the wire harness for damage to engine ground.
good luck
It sounds like an O2 censor, If it happens when your around that speed it could be the map censor or the 02 censor. You need to go to a garage and have them hook it up to find out which 02 censor is causing it.
Try replacing the crank sensor and relearn the idle air control.The sensor is in the back of the motor.They tend to crack and this will cause stalling.Hope this helps.Good luck.
It sounds like your not getting fuel you may want to get the map censore checked it controls the fuel and tells the fuel on which way to go. It sits on the top of the engine and its right hooks up to the injection system.
when the engine light blinks it normally indicates that there is danger to the catalytic converter check the map sensor and both o2 sensors again and also check to see if the converter is clogged
The O2 sensors are found on the exhaust pipe. They screw into the pipe and has wires coming off of them. The MAP sensor has a 3 or 4 wire plug with a vacuum hose connected to it commonly found on the intake or firewall.
