Hi, so a month ago my car was having problems. It was shaking and the engine light was on. I figured it was an ignition coil and i changed the one not working after consulting with a mechanic. But the problem still didn’t fix. I then changed all the spark plugs and my car started working good. Now after a month i have the same problem, my car is shaking. Do i change all 4 of the ignition coils?

    Use scan tool to see if it’s only one plug misfiring. Also pull the plugs to compare them to see if one’s different.
