Won't Start!!!

[mustang93]

Thanks for the info. I have another question. Today we played around with different computers. The one that was in the car came with the motor and I was told that it came out of a 93 5.0 with a manual transmission. I was also told that it didn't make a different whether or not the computer came out of an automatic or a manual as long as it was being used in a manual. We put another computer in my car that came out of my friends car and my car ran fine for a while and than started doing the same thing again. We than took my computer that was in my car and put it in his and his car ran fine with my computer in it. Do you know if there is a difference between an A9L computer and A9O Computer. My car has mass air and I know that you have to have a computer that is for mass air. But is it true that it doesn't matter which type of computer you have to use.

Thanks in advance
