1987 Mazda RX7 Two Wheel Drive Manual 147000 miles

I have an 87 Rx7 gxl non-turbo and it has a miss in the motor that I can't figure out how to fix. I feel it may be causing bad gas mileage and taking some of my horsepower away. How can I fix it?

Hello and thanks for donating

There are many things that can cause a misfire in the engine. Has your engine light appeared? If so is there any codes aside from a misfire codes? It could be sensor causing the issue, sticky valve, weak spark plugs, dirty fuel filter and much more. What all have you already checked or replaced?
