What causes fuel injectors in Mazda Miata to go bad?
There are two main ways that your injectors can go bad. The first is for them to become clogged, dirty, or unresponsive. When this happens not enough fuel enters into your Miata’s combustion chamber. The other way is if the injectors are leaking.
Why does my Mazda Miata smell like fuel?
Any gas that is not fired and sent out as exhaust ends up in the oil pan. When this happens it can decrease your Miata’s engine lubrication to the point that it’ll lock up. You will smell fuel on the dipstick. The Smell of Fuel – When your engine is getting too much fuel, your Miata can’t burn it all.
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.

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.

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.
