What does warm engine mean on Mazda Miata?
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. The troubleshooting I’ve done here is specific to a 1.8L 1995 Miata, you may apply what I’ve done here for your application.
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 RPM of a car when it idles?
When the car starts it idles fine at about 1000 RPM. As soon as it warms up, it starts to idle rough, between 500 and 750 RPM. It almost quits running. As soon as you give the car some gas it runs just fine.
Why does my Mazda 626 shake when idling?
I’ve got a 1999 Mazda 626 that shakes really badly when idling. It gets a little better when put into neutral, but not much. I’ve had two people suggest possibilities: This started happening in the last year or so. It started out being a mild shake when stopping at a stop light, but in the past 6 months or so it’s any time the car is not moving.

What should the fuel pressure be on a Mazda Miata?
Connect a fuel pressure gauge (About $60 at your local auto parts store) to the high pressure fuel line. The high pressure fuel line is the rearmost of the two metal lines (passenger side of engine), pictured. Pictured below is the pressure I read off the fuel pressure gauge. The Haynes manual states between 32-38 psi is normal, at idle.
Why does my car idle at a higher RPM than normal?
Updated January 19, 2019. If your car seems to be revved up to a higher-than-normal RPM while idling, it’s not necessarily a problem. If this problem happens while the engine is cold, it may be part of the engine’s design.
