Hey can someone help out. I have a 91 miata and it sounds like it's misfiring at about 1500. Only when I step on the gas pedal and sometimes when I drive and let the rpm drop it drops under idle and sometimes even turns off. Does any one have an answer
Sounds like you need to replace spark plugs and wires. Might want to check the plugs for oil, mine misfired at about 1500-2000rpm and had oil on #3 and 4 plugs. I needed a new valve cover gasket and wires/plugs, fixed the misfire.
I have the same problem - I changed the wires and plugs with no change......
