Ok, so I have the bad codes of 83, 84, 85..................and 28. I know what they all are and what the potential price will be to fix it
Anyway, just wondering how in the heck do I pull the EFI fuse??? I know it cant be that hard. I have pulled the side latches and still cant lift if off. Any ideas????

BIG PROBLEM!!!!!!!!!!!!!!!!!!!!!!!! Sooo, I have been researching the problem with the early 1993 (pre production date 05/93) I thought this was my problem and that I would need to find a new (used) ECU. Well, I just went and checked my rig. Here is what I found............my ECU has the correct number (89661-60221) which is the newer one, and the production date on my beast is 06/93. So, I am at a loss as to why I am throwing the codes 83, 84, 85 and now 28 (which I heard happens at times when throwing the previous three codes).

Basically, can anyone give me a link (I remember something about Slee doing a write up on what the potential problem could be). I seriously need some help on this. Thanks in advance,
Chans

Hmmmm, no need to purchase a code reader since I know what the codes are. Just need to figure out why they are coming on since all the "normal" parts are correct and or replaced. But thanks!
