Why is my Miata engine not idling properly?
There is another possible cause for hesitation and poor idling: Water in the engine – if you clean the engine bay with a pressure hose and spray the top of the engine block, you may have troubles. The rubber seals on top of the spark plugs aren’t so great, so some water can seep into the cylinders, particularly the no. 1 cylinder.
Are there any problems with my 1995 Mazda Miata?
Talk about Miata problems and share solutions with other owners here. My 1995 Miata had only 3900 miles on it when I bought it in ’97. I drive it only about 3000 miles each year and store it over the winter. About 4 years ago the engine developed a hiccup, especially at slow speeds. Also, there’s a strong exhaust smell in the trunk.
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.
Are there any problems with the Mazda Miata?
I going to buy a 94 miata with 88,571k miles on the car. My mechanic said that the only problem with the car is that the oil pan begin to leak and it needs to be change. does anybody know how much will this cost to replace the oil pan or (gasket). and will the insurance be really exspensive because i’m a 17 yrs olds male.
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.
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.

Where can I get an ignition coil for my Miata?
Fortunately, we found a coil assembly from Mazmart in Atlanta for only $125. Now the car runs fine. The point is, don’t do a compression check without either pulling the connectors from the coils or keeping a spark plug in the wire while turning over the engine.
Why are the spark plugs on a Miata not straight?
The ceramic insulator on the spark plug has straight sides – not ridges like the factory NGK plugs. As a result, the rubber boots on the spark plug wires sometimes grabs the ceramic insulator so tightly that the boots stay behind when the wires are removed.
How long do ignition wires last on a Miata?

What do you use to grease the plugs on a Miata?
Apply Silicon Grease to inside of bottom seals of plug wires (i.e. inner surface of plug wire which mates to the ceramic insulators on the plugs)
What are the specs of a 1993 Mazda Miata?
Brilliant Black w/red interior only, B package plus BBS wheels, red interior, carpet, floor mats, leather seats, rear lip spoiler, rear lower skirt, front air dam, doorsill plates, Nardi shifter, key fob, Bilstein shocks, red vinyl tonneau cover, ABS, MSSS (Mazda Sensory Sound System) with CD player and polished door speakers covers.
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.
How do you check the ignition on a Miata?
An easy way to check is, pull #1 spark plug, and drop the dipstick down the hole. Turn the motor by hand and watch the dipstick until it peaks at top dead center. This will tell you the crank shaft is at TDC. Now check to see where the timing mark on the crank pulley lines up.

Where is the high pressure line 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.
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.
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 kind of engine does a Mazda Miata have?
The 1.6 Miata started with an 85kW iron-blocked engine derived from the turbocharged engine used in the 323 GTX all-wheel-drive car. With 114 horses, pulling this energetic roadster, 0-100 km/h acceleration is possible in 8.3 seconds. This engine featured lighter crankshaft and flywheel, as well.
What’s the difference between a 1.6 and 1.8 Miata?
Let’s go through some basic facts and see how much of a difference there is between the two models and why these roadsters still represent such a hot topic. The 1.6 Miata started with an 85kW iron-blocked engine derived from the turbocharged engine used in the 323 GTX all-wheel-drive car.
Why is my Miata engine cranking but not starting?
It really can get that one last start out of it. There are a lot of issues that can cause your Miata to crank, but not start. The engine needs air, fuel, and a spark in order to run. It is highly likely that if the engine is cranking, but not starting that it has thrown an OBDII code.
