ENGINE SHAKES AND POPS WHEN ACCELERATING

1992 Mazda Miata • 146,000 miles

Car shakes when accelerating and if accelerating too quickly pops are heard from the engine. After reaching cruising speed no shaking or popping is heard it runs smooth.I have changed the spark plugs out and it seamed to fix it for about a week then the problem started up again I have also taken off the valve cover and resealed the gasket with no improvement any ideas where to go from here or any ideas on what might be the problem.

thanks,
