A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.

1991 Mazda Miata MX-5 Problems
Failure of the valve cover gasket can allow engine oil to leak onto the spark plug wires and damage them. The engine will run poorly (misfire) if the spark plug wires fail.
The engine may idle roughly or stall when it's cold because the oil pump pressure relief plunger is sticking. Failure is usually due to wear and it causes excessive oil pressure to pump up the hydraulic valve lifters keeping the valves from closing completely, which results in a loss of compression. The oil pump will need to be replaced in this case.

Misfires under load (acceleration) can be caused by spark plug wires arcing to the cylinder head in the spark plug wells. Water in the spark plug wells can also cause the same problem so careful diagnosis is needed.

1991 Mazda Miata MX-5 Reviews
I've owned my 1991 Miata for ten years and am the second owner. I have owned a lot of cars over the years, before and since the Miata, but this is the only car I have kept for a long time. I simply cannot bring myself to sell it. It requires almost nothig yet gives back so much. It's fun, economical, nearly bulletproof (only problem to date other than maintenance was a power window motor... not bad for a 17-year-old car). If you are looking for a fun commuter car, a used Miata cannot be beat. If you are looking for a low-cost way to star racing, a Miata is terrific.
The only downsides are really just inherent with light-weight sports cars - noise at highway speeds (I used foam earplugs on a cross-country trip), lack of storage space (but actually not bad for a car like this... I can fit a golf bag in the trunk or 5 large grocery bags), and a choppy ride.
