I'm GW. Do you still have the misfire? Did it leave the shop with a misfire? Is the ck eng lite back on?

yes it left shop with misfire ch eng lite back on
Expert:  Golden Wrench replied 8 years ago.
OK. Was it actually misfiring? You probably have an ignition coil down. Have the shop check for spark at the coils. Common problem.
