If the automatic transmission shifts in and out of overdrive while cruising, it may be due to the thermostat that is stuck open. The 323 transmission is especially effected by the engine running too cool. If possible, check to see the engine is running at full operating temperature while cruising. The temperature gauge in the 323 may also read normal when the engine is not reaching normal operating temperature.

1993 Mazda 323 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.
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.
If the engine cranks but does not start, and diagnosis shows no fuel pressure, the fuel pump relay is frequently the problem. If the fuel pump relay is defective, the fuel pump will not energize and therefore, not generate fuel pressure so the engine can run.

1993 Mazda 323 Reviews
OK, so this car isn't as nice as a Honda Accord, Honda Civic, or even the nicer Mazdas like the 626 or MX-6, but these Mazda 323 cars run like champs. Take a licking and keep on ticking. This car was almost never in the repair shop. It needed the basic engine maintenance and brake jobs, but other than that there were nno problems. It's not going to win you any dates or turn any heads outside the club, but it will get you to the club every time when other people are walking or riding with a friend. Simple, basic, great car.
