i was leaving church this morning and i pulled out on the highway and the car was acting real sluggish sounded like it was spinning but wasnt actually doing anything. i was like ok its just that the road is wet got halfway home and the engine light started flashing so turned around went to advance and put a code reader on it. threw the po358 ignition coil H primary/secondary circuit malfunction. what does this code mean and what do i need to fix? your help is greatly appreciated.
