I was driving my 2001 Mazda 626 6 cylinder on a highway up a not very steep hill when it the engine shook and the check engine light came on. It stopped shaking when I slowed down, but it started again after I got a little above 2000 rpm or about 60 mph. I stopped and put it in park and started again, and the problem happened again for about 2 seconds, then went away. My only guess is the ignition coil. Any ideas?
