Got my first data log... well kind of.
Before it caught on fire I got these numbers. It runs sooo rich and won't idle. I didn't get it fired up but this is what I got while it was cranking...

Sorry for the bad screen shot... Is there any way to show the aldl stuff without pasting the screen shot to paint?
to fill in the blanks IAC was 100, INT was 128, MAP was 98.9 kpa
Any suggestions for getting the thing to idle or start? Ever since I put a muffler on it won't fire up like it did with open headers. I've already changed the bpw using a calculator and I pulled all the timing advance out to so I can get a baseline idle.
I'm think IAC but I don't know what to do. I need to lean it out at low rpm. Can I do this with the IAC?

Edit: I just noticed you said you got those readings while cranking the motor, that won't tell you a thing. You really need to get your injectors fixed before you go any further.
