Hi, a recent problem has come up on my 85 corvette. One day it was running fine, then when I went to start it back up it wouldn't idle. It still ran fine when I didn't let off the throttle. Then it started running like crap. I checked the codes and got 33 and 51. So I changed the mass air flow sensor. That got it running right but it still wouldn't idle by itself. I read that someone's ecm had gotten water damaged and that it wouldn't idle either. They said they had water on the passenger side floor. My passenger side floor was fairly damp one time but I just thought it was because of my shot weather stripping. Do I need to replace my ecm or is it something else?
Thanks,
Dan
