Can you add ECU plugs to a 1996 Miata?
At this time we do not have an ECU that accepts the 3 ECU plugs of the OBD2 cars. Therefore, the ECU wire harness in ’96 and ’97 Miatas must be modified to a ’95 Miata wire harness. The first way to do this is to obtain an ECU wire harness from a junk yard. The plugs and about 12” of wire is plenty to splice onto the wires in the car.
What to do if your Mazda Miata wont start?
You may also try cleaning the MAF by putting it in a large GLAD bag with alcohol and shake the bag to completely coat the MAF. Remove and be sure to let COMPLETELY DRY before re-installing otherwise you may damage the internal electrical components if you try and start the car before dry.
Is it possible to fix an ECU in a car?
Fixing up most car ECU problems and what to do! Now, getting an ECU or ECM repaired is not a piece of cake because it can’t be fixed just like that in a jiffy. Any attempt to open or mess with an ECU or ECM will end very badly. It houses the software and hard drive that controls all the functions of a car engine.
What kind of car is a 1995 Miata?
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. This may have been a problem that has been stewing for awhile but became such an issue at Hallett this past summer that I had to solve it.

How long do ignition wires last on a Miata?
Hesitation 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.
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).
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.

What kind of audio system does the Miata use?
Mazda has a long relationship with Matsushita/Panasonic, so Miata audio systems from 1990 through 2000 are based on Panasonic designs. Descriptions of pinouts for these systems are found in the first partof this FAQ. In the early ’00s, Ford and Mazda partnered with Sanyo to design a new modular audio system.
Why is my spark plug not working on my Miata?
Change the wires! In case you forget which plugs is which, refer to the firing order diagram below. This is caused by breakdown of the insulation on the wires which results in the spark arcing through the insulation to the metal valve cover instead of through the spark plug electrodes.
How long do ignition plugs last on a Miata?
OEM plugs usually are somewhere in the middle. 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!
Why does my Miata make a pinging sound?
Pinging occurs when the fuel mixture in the cylinder ignites and completes its burn before the piston reaches the maximum compression point in its travel. It sounds as though a handful of marbles were dropped into your engine and generally occurs under hard acceleration under load. There are several possible causes of pinging.
How does the diypnp work on a Mazda Miata?
The DIYPNP allows you to disconnect the Mass Air Flow meter. When you remove the MAF, you will need to install a GM style intake air temperature sensor in your intake. The IAT sensor on NB Miatas has a separate plug with two wires, as shown in the photos below.
