Question about 1991 Mazda 323
Hi, I`m driving a Mazda 323 from 1991. Recently I`ve been experiencing problems during acceleration. The car seems as if it`s going to die then it jumps. The problem isn`t always present, it seems to be more frequent when running lower and lower on gas, but not even on reserve. So, what do I do? Thanks for your help

Is the engine light on? Check the air inlet hose between the throttle body & MAF sensor for cracks or leaks. Try unplugging the MAF & see if there is any difference

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.

Testimonial: "Very fast and detailed response makes it easy (for those of us who aren't savy in automotive repairs) to understand. "
SOURCE: Losing power
Check the output from the alternator to the battery,with everything on,lights,and ac,high blower motor setting.It should read 13.65 volts,to 14.25 volts,if it is lower than this,then the alternator is bad,just because the battery maybe starting the vehicle good,and seems strong,does not mean the alternator is working correctly.No days,vehicles ignition/computer systems need a good bit of voltage to run the car,and charge the battery.

You might try another mechanic if this one can't get it fixed. Shaking is usually caused by one or more cylinders mis-firing for whatever reason--usually faulty ignition or fuel injection. Has the engine had recent tune-up? Bad spark plugs/plug wiring are frequent villains. Not sure what an 'OS2' code is. Hope this helps!
