I have almost every light lit up on the dash that can be on. I've got the same code both times its been diagnosed P0306. I've had it worked on 3 separate times since. The first time they changed the coil pack. The second time they changed the injector. Third time they fixed a seal in the vac line. The dash lights were still on but they assured me it wasn't misfiring and was running perfectly. I was told by the Meineke manager that my G1 needs a software update and that should fix the dash lights. I've been trying to research the update for the G1 and I dont see one. Any suggestions?
