I have a 1990 Mazda Miata. It starts when it wants to. Been running fine. Get up in the am won't start. Push her off starts fine for a week or so. Go to the store come back won't sart, push her off starts fine for 2 weeks. Last night went to the races after the races had to push her off. This morning she is starting fine again. I keep this up and won't have a rear bumper.

When was the last time spark plugs were changed? If not in the last three years, you might want to replace with the brand originally in your car. Also might want to check and/or replace the ICM or "Ignition Control Module".

Thank you, Will try and see.
