How long do Miata timing belts last?
Although timing belts are critical, there’s no need to replace them regularly –unless explicitly recommended in your MAZDA owner’s manual. Some automakers recommend changing a timing belt between 60,000 and 100,000, others don’t. Many of today’s timing belts can go 100,000 miles or more without needing to be replaced.
Can a timing belt break on a Miata?
The Miata engine is a non-interference engine, meaning that the pistons will not crash into the valves. However, if you neglect this major service, you risk being stranded due to a belt break. WARNING: Changing your own timing belt is not for the faint of heart!
What to do when your Mazda Miata starts from cold?
This normally occurs within two minutes with the engine started from cold, and can be observed by a noticeable drop in rpm at idle. With the engine warmed up disconnect the pig tail wire of the O2 sensor from the main engine wire harness. Repeatedly and quickly apply large amount of throttle. If throttle response is normal, replace the O2 sensor.
What to do about bogging on a Mazda Miata?
With the engine warmed up disconnect the pig tail wire of the O2 sensor from the main engine wire harness. Repeatedly and quickly apply large amount of throttle. If throttle response is normal, replace the O2 sensor. For me, I still had the “bogging” and misfires.
What does advanced timing mean on a Miata?
Advanced timing means that the spark which ignites the fuel mixture in the cylinder occurs before the piston reaches top dead centerof its excursion. Factory spec for the Miata specifies standard timing as 10° before top dead center (10° BTDC) ±1° at idle speed(850 rpm).

What should the idle RPM be on a Miata?
Factory spec for the Miata specifies standard timing as 10° before top dead center (10° BTDC) ±1° at idle speed(850 rpm). If your timing is advanced more than this, you may experience pinging under some conditions. Dirty spark plugs Metallic burr in cylinder
Why does my Miata keep stalling and stalling?
If your Miata is running unevenly, sometimes stalling, sometimes hesitating, there could be another problem. Your timing belt may have jumped a tooth or worse, your crank shaft may be broken.
