Car shuts off at low speed - 1998 Pontiac Grand Prix

I was expericing a similar problem on my 98 GP. The problem was simply a corroded battery cable, It seems when the cable becomes corroded it would shut the car down at low speed. I cleaned both terminals and battery post (side mount battery) replaced the post screws and added a dab of no corrosive lube.
I have not had a problem with my car shutting off since then.
Hope this helps you.

Went to Autozone, had the error diagnosed, the MAF Sensor was replaced based on that diagnosis. Car is running fine now. I

I believe this occured because when I had my most recent Oil Change done at the station, they checked to see if the air filter needed replacement and did not properly reconnect the air hose leading to the filter. The hose slipped partially off the connection to the air filter, therefore facilitating infiltration of dirty air and dirt particles, which then led to the sensor shutting down the car. I did not notice right away that the hose had not been properly reconnected and only discovered this when I noticed the car running roughly after a while.

In the future, I will always look under the hood before leaving any shop to ensure everything has been properly reconnected. Hope everyone does the same, I was lucky that only the sensor was affected and I did not get any dirt into the supercharger.

Thank you for the help.

I have a 2006 buick lucerne 3.8 v6 cxl.my coolinf fans dont come on .i need to know how to change the relay and the fuse.


Your vehicle cooling fan's are controlled by three relay's , couple of fuse's an the PCM - engine computer . The engine coolant temp. sensor is a input to the PCM , when engine temp get's to 212 the PCM will turn on the cooling fans in low speed . Checking to see what the actual temp is with a scan tool an a infrared thermometer at the thermostat housing ,an looking up the specification's in a service repair manual is how to diagnose . Not guessing an replacing parts . Plus learning how the cooling fan's work .
Relay Driven Dual Cooling Fan Diagnostics Reading factory service info as to how they work also would be a good idea .

Cooling Fan Control - Two Fan System
The engine cooling fan system consists of 2 puller type electrical cooling fans and 3 fan relays. The relays are arranged in a series parallel (S/P) configuration that allows the engine control module (ECM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block. The ground path is provided at G104.
During low speed operation, the ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the low speed fan relay coil, closes the relay contacts, and supplies battery positive voltage from the low fan fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan S/P relay and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the ECM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. After a 3 second delay, the ECM supplies a ground path for the high speed fan relay and the cooling fan S/P relay through the high speed cooling fan relay control circuit. This energizes the cooling fan S/P relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time, the high speed fan relay coil is energized closing the relay contacts, and provides battery positive voltage from the high fan fuse on the cooling fan motor supply voltage circuit, to the right cooling fan. During high speed fan operation, both engine cooling fans have their own ground path. The result is a parallel circuit with both fans running at high speed.
The ECM commands the low speed cooling fans ON under the following conditions:
• Engine coolant temperature exceeds approximately 94.5°C (202°F).
• A/C refrigerant pressure exceeds 1447 kPa (210 psi).
• After the vehicle is shut OFF, if the engine coolant temperature at key-off is greater than 101°C (214°F), the low speed fans will run for a minimum of 60 seconds. After 60 seconds, if the coolant temperature drops below 101°C (214°F), the fans will shut OFF. The fans will automatically shut OFF after 3 minutes, regardless of coolant temperature.
The ECM commands the high speed fans ON under the following conditions:
• Engine coolant temperature exceeds approximately 104.25°C (220°F).
• A/C refrigerant pressure exceeds approximately 1824 kPa (265 psi).
• When certain DTCs set
At idle and very low vehicle speeds the cooling fans are only allowed to increase in speed, if required. This ensures idle stability by preventing the fans from cycling between high and low speed.

Ac works while traveling at low speeds quits working after higher speeds


Can you replicate this in the workshop by raising the engine revs with the pressure gauges attached to he high and low sides? What is the maximum high pressure you see before the system shuts off?

Try this

Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

I have aVW jetta 4, 2.0 highline, 2001 that stalls engine at low gears. The situation becomes worse when the aircon is on.

My 1990 Toyota corolla just shuts down when my air condition is on


IDLE SPEED COULD BE TOO LOW.IDLE SPEED SHOULD BE 800 RPM. IF IDLE SPEED TOO LOW AND ENGINE NOT WELL TUNE UP AIR CONDITIONER WILL PUT LOAD ON ENGINE CAUSE ENGINE OVER HEAT AND SHUT OFF.

The vehicle engine is shut off immediately when you release the acceration pedal


PROMLEM MAY BE BECAUSE LOW IDLE SPEED ADJUSTMENT. INCREASE THE LOW SPEED/ IDLE SPEED BY INCREASING THE FUEL INTAKE . IN CARBURATOR VEH. ADJUST THE IDLE SCREW CLOCKWISE. IF IT IS FUEL INJECTOR INCREASE THE FUEL AT PUMP ITSELF.

Car would not start so replaced battery, then alternator; Ran great for roadtrip then shut down on the freeway. Can hear the fuel pump, so replaced the fuel filter; has spark. Has fuel. Wires are in good...


WHEN A CAR SHUT DOWN ON HIGHWAY OR FREEWAY.YOU CAN STILL HAVE FAULTY FUEL PUMP.IT COULD BE RUNNING BUT THE FUEL PRESSURE CAN BE TOO WEAK.THE 2.5 ENGINE FUEL PRESSURE IS 6.0 TO 7.0 PSI AND THE 3.3 ENGINE FUEL PRESSURE IS 37 TO 43 PSI. ANOTHER THING CHECK TO MAKE YOUR COOLANT IS NOT LOW.LOW COOLANT CAUSES ENGINE GET TOO HOT SHUT OFF.CHECK PVC VALVE AND EGR VALVE MAKE SURE THEY ARE NOT STUCK OPEN OR DISCONNECTED.AND MAKE SURE IDLE SPEED IS NOT TOO LOW YOU IDLE SPEED IS ON THE FACTORY STICKER UNDER THE HOOD.
