Question about 1999 Mazda Protege

1 Answer

When starting the car, its runs fine for a moment then it seems like when the motor starts warming up it is right on the brink of dieing so i then have to feather the throttle to try and bring it back

Now when driving it sounds as if it is spitting and sputtering trying to die. it will still sound ok though when i am not in the throttle. The morning it started all of this i acted as if the battery was dead. I took the battery out of my car and put it in my truck and it started my truck up just fine. I hope you can help me narrow this down

SOURCE: 1991 Mazda 626 DX dies suddenly after running for 10 minutes.

Hello, It sounds like an engine ignition control module gone out or a coil. They get hot and quit working after a short period of time, cool off then work again till they get hot.
Is the ignition system pointless electronic or does it have points? Are you getting any fire at all now to the cylinders? Does the tach in the vehicle show any RPM's during cranking? Do you have voltage at the positive side of the ignition coil? Does the coil meet the ohm ratings for that years vehicle ignition? Does the vehicle have oil in it so the oil pressure sensor allows the engine to run, this may not be an option on your particular vehicle? You can check most of this out with a volt/ohm meter. Check your voltages before starting the vehicle, during running and after it quits to see where the loss is. Just don't get near the center tap of the coil or you will get a rude awakening and/or serious injury. Good luck, RAC

SOURCE: Sounds like it's going to die until it warms up...

Katrina, the fact that your car runs (like a beauty) when shes warmed up, indicates a fuel air mixture problem when cold. Your car is equipt with electronic fuel injection. This system utilizes a series of sensors that detect conditions such as engine temp, outside temp, humidity and air pressure to determine what mixture is perfect for the prevailing condition. For example, on a cold start, the sensors should know that the engine is not up to the proper operating temperature and provide more fuel and less air, (a richer mixture), until the engine warms, this emulates a choke on a vehicle equipt with a carburator. The problem either lies in the sensor itself, or the brain that interprets these inputs to decide what fuel/air mixture to deliver.

Before you replace the fuel pump, I would check the cheaiper parts first. Such as fuel filter and injectors.

if there is electronic throttle then probably needs replacement, get second hand one , or otherwise can try to take it out and clean it, if there is an access to electronic part of it try it open carefully and clean contacts with some alcohol, sometimes it helps
