I sure hope someone can help me.
I drive a 1997 Mazda Miata. I bought it twelve years ago and drove it everyday for about six.
But then life happened and it sat for about five years in Southeast Alaska and had numerous problems as a result. I have fixed all of the problems save one that has even my engineer friend puzzled.
It idles fine, it runs fine for about an hour; then it just starts to loose power every time I push in the accelerator. if at this point, I engage the clutch, the engine revs normally. Once I put the load back on it starts to hesitate again. Sometimes this goes away and sometime it keeps happening to the point where it is a little scary. It has never actually died on me. Once I let it sit for an hour or so it runs fine again for a while.
I have changed the plugs, plug wires, fuel filter, air filter and drained and flushed the fuel tank...
Any thoughts?
