Misfire and/or Check Engine Light Due to Failed Ignition Coil on Toyota 4Runner

coil failed, caused a misfire. The spark plug blew out and knocked off the oil cap. made a lot of noise and a big mess. $1700 to fix at Sterling McCall Toyota in Katy
My car was shaking and felt like it was going to shut off. The mechanic replaced both coils for a little over $300. Seems to be working fine.
