Shops wasted thousands trying to fix Miata but then after two years Missouri man fixed it with ease

This Missouri man, who runs a salvage business, is known for never taking on side work, but when this Miata owner comes to him with a problem that shops had wasted thousands on, he couldn’t help but fix it.

The car had been exhibiting multiple issues with various things, especially high idle, misfire, and oxygen sensor issues.

Multiple shops had replaced the airflow meter, the oxygen sensor, the idle air control, and the fuel pump, but none of the changes worked.

The Missouri YouTuber has a lot of experience with Miatas, so the owner turned to him to fix it, and it turns out he did it with ease.

You can’t help but feel bad for the owner of this 1997 Mazda Miata, Mason, as the car was running really poorly and he’d taken it to multiple shops without a successful repair.

The car had diagnosable problems in the form of high idle, misfire, and oxygen sensor issues. And every shop had a stab at fixing it, but to no avail.

They’d replaced the airflow meter, the car’s oxygen sensor, the idle air control, the fuel pump, and even cleaned the tank. Nothing has worked, meaning that Mason went to the I Do Cars garage in desperation.

Even though the YouTuber from I Do Cars is known for running a salvage business and never takes on side work, he felt sorry for Mason. He knew he needed to help with his Miata, as he had experience with them.

The Missouri YouTuber used a timing light to diagnose some issues because he realized that the cam angle sensor was maxed out in adjustment, suggesting potential timing problems.

He also realized that the Woodruff key was damaged. But after using the timing light, he found that the Miata’s exhaust cam was actually one tooth out of alignment.

The YouTuber replaced the Woodruff key with a factory part, as well as the timing belt, cam seal, and valve cover gasket. But he left the water pump as it still looked functionally ok.

None of these worked, though. So he also replaced the intake tube, fixed a coolant hose leak, and addressed the wiring issues.

Suddenly, he noticed that the fuel pump and hose were incorrectly installed.

When he replaced them with proper factory ones, finally, the car ran normally once more. And Mason was able to bring the working Miata back home where it belonged.
