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?

Scan for codes it may have one stored in computer. Or maybe you got some water or liquid on it to do that or mayb e apiece of junk got intot he spark plug like carbon then cooked out.

Check ur ignition coil, ether 1 ov them is not working. Try to remove spark plug cables 1 by 1. Iv the spark is fine but stl shaking. Then check the following, spark plug, vaccum leak, temp sensor, catalic conveter/mufflur. Iv all fine then get a scan tool.
