Why was the Mazdaspeed Miata a one hit wonder?
Mazda only made about 5400 Mazdaspeed Miatas, DrivingLine reports, due to a production-facility fire. And due to that rarity, plus the factory upgrades, they’re a bit pricier than most NBs. For context, I paid less than $7000 for my 1999 10 th Anniversary Edition NB a few years ago.
Why is my Mazda Miata bogging at 4000 rpm?
My issues were primarily below 4000 rpm, and after the engine had warmed up. Throttle response was seemingly normal across all rpm ranges with a cold engine. With a warm engine and above 4000 rpm the acceleration seemed normal. A warm engine is indicated by the O2 sensor sensing a warm exhaust manifold.
What’s the throttle response on a Mazda Miata?
This is somewhat of a common problem for this generation of Miata. My issues were primarily below 4000 rpm, and after the engine had warmed up. Throttle response was seemingly normal across all rpm ranges with a cold engine. With a warm engine and above 4000 rpm the acceleration seemed normal.
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’s the top speed of a Mazdaspeed Miata?
A top-gear 50-to-70-mph time of 7.6 seconds is pretty respectable and four seconds better than the 142-hp model’s. On a purely subjective level, the Mazdaspeed car feels wholly transformed, capable of top-gear traffic slaloms at just a jab of the pedal.
When did Mazda change the transmission on the Miata?
It’s said that Mazda improved the transmissions in 1994 for the updated NA8 drivetrain. The big change came in 1999 when the NB chassis arrived. Mazda redesigned the transmission and it is the transmission of choice for Spec Miata racers, as it shifts smoother and is stronger.
