Hey guys,
Sorry for the delayed response. I had to work and am just getting back to my computer. First, I want to thank everyone for your help. It is greatly appreciated.
When I had it in the shop, the mechanic pointed out a hissing sound just behind the air cleaner. He sprayed something behind the air cleaner and the hissing stopped and the idle became better. A short moment later, it went back to hissing and the idle became erratic. As to what exactly is leaking, I don't know, but he said that the MM EFI had to be replaced. He told me I could put in another MM EFI, but that I may or may not have the same issues down the road. He also suggested I look into the thundermax. Whatever it was, he was convinced that the MM EFI had to be replaced. I hope that answers the questions.
Geargrinder: If I do have to replace it, then yes I am interested. I will pm you.

Nope. The rubber seals between the heads and the intake body. Unless the throttle body somehow got cracked, there's not many spots it'll leak from.

I agree, it sounds like the seals from the intake to the heads is bad. I would get it away from that dealer, sounds like they don't fix anything, just replace it.
