Prom problem?

[Dan Townsend]

Well I'm having a slight problem with the 749 code in the 730.  Seems when I
swap chips the ECM wants to get a check engine light and run like total
crap.  I pull the power and EPROM and swap everything back and forth and
after a couple times and then it works.  Anyone know a way around this?
Like something that works almost all the time.
