92 sc400 codes 14 and 15
So i have been searching all day and im stumped. I started my car this morning and its running fine. Go to leave for work put it in gear and it has a misfire. so turned it off did some searching checked the codes and got 14 and 15. seen similar problems where the car doesnt run but mine still does and if i let it sit for a bit start it and it runs fine again for a few minutes or you put it in gear then misfire. im really confused has been running no problem then this. any help would be appreciated thanks

It's also a good idea to check for a faulty ground connection on the engine block. I believe the ignition and efi grounds are connected on the back of the left cylinder head.

So went out started it ran fine had to wait about 5 minutes with it running till it started misfiring. Tried unplugging the coils and the car died both times. Not sure what that means.

been trying to search for grounds. did they decide to hide a few? someone said that there might be moisture in the gas tank cause when missing it runs fine for a minute then misses then fine for a minute then misses again.. or could it possibly be my altenator going out on me and not sending the right amount of juice to the system?
