The timing belt tensioner pulley may make a squealing noise from the timing cover area on cold startup. An updated tensioner with a thicker mounting bracket to eliminate vibration may be needed to solve the problem.

1991 Mazda Protege Problems
Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. New spark plug wires will be needed.
An electrically shorted air flow sensor can cause a crank-no start condition. Diagnosis may show that ignition spark is normal, and there are no trouble codes stored.
A loose or corroded ground terminal on the driver's side of the cylinder head can cause a rough idle, misfires, and there may be trouble codes. Restore the ground to the cylinder head.

1991 Mazda Protege Reviews
I Love this car, i bought my 1991 protege from the original owner about 31/2 years ago with only 60,000. I have not had any problems with the car just the normal stuff, tune ups, brakes, i replaced the horn but that is about it. I am now just replacing the water pump and thermostat but other than that the car is solid. This car can run for another 20 years because it only has 85,000
