car was running fine yesterday...

I recently put a new motor in my 99 camaro its a fully built 370 H/C/I longtubes CAI 42# injectors. I have not been driving the car cuz i havent had it tuned but lastnight i started it and back it out of the garage to do some cleaning and move stuff around and it started and idled no problems just rich as hell. Well today i went to back it out again and it wont hardly start and it refuses to idle. I cant even keep it running good enough to back it out. Im goin to have to push it. Is this just in the tuning? Or is it something else. Seems weird that it runs one day and wont the next. Let me kno wat you guys think. Thanks ls1tech.

Well SScooter, you have the equivelent of 49# injectors with a PCM that thinks they are 26#. I'm sure your plugs are nice and sooty black from running it that way.
