Why does my Miata stall out at idle?
It has 90,000 miles on it. Lately I have had a problem with the car stalling out at idle (when I stop for a light ) This is after I have driven it long enough to heat it up completely. It starts right back up and until today it would make it home without a problem, but today it continually stalled out. I did make it back home.
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 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.
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.
Why does my 2005 Miata start and stall?
My 2005 Miata (non-turbo) started idling poorly, then progressed to stalling, and the Check Engine light came on. It sure seemed like a sensor problem. I had the codes read. There was a fair list of them. I reset the faults by momentarily disconnecting the battery. The faults came back. So I started replacing the likely sensors. Nothing helped.
Is the Mazda MX5 stalling out at idle?
I’ve had my 1992 Mazda Miata MX5 since 2009. It has 90,000 miles on it. Lately I have had a problem with the car stalling out at idle (when I stop for a light ) This is after I have driven it long enough to heat it up completely.
How often does my Mazda Miata lose power?
Occassionally, I start my ’99 Miata and the engine idles poorly, it revs up with difficulty, but it runs. Then I take it out on the highway, and after 10 minutes it starts losing power and the catalytic converter gets so hot I can smell it inside the car. This happens once a month. The runs again the next day.
What is the control system on a Miata?
This system consists of the air valve that functions only when the engine is cold, the ISC valve that works throughout the entire engine speed range, and the control system. The “control system” mentioned in this description is primarily the ECU (Engine Control Unit).

What’s the standard idle speed for 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.
What happens when gas is too low in Miata?
Fuel octane is a measure of the ability of the gas to spontaneously ignite. (For more information on octane, see the Gasoline FAQ.) When the octane is too low, the fuel in the cylinder burns too quickly causing ping. The stock Miata is designed to run on 87 octane fuel.
Why are the ignition wires on my Miata not working?
Common Problem! The factory ignition wires on the Miata only seem to last between 30,000 and 50,000 miles. If you are experiencing misfiring and hesitation and you haven’t changed your wires, this is most likely the cause. Change the wires! In case you forget which plugs is which, refer to the firing order diagram below.
