i realized it wasnt posted the most ideal category so i reposted it here but was unable to delete the old one. Yes, my computer is an OBD 2 not an OBD 1, this i know for sure.

95 is OBD1 which would also explain why the OBD2 scanner couldn't read it as well as why you may be having problems with the tune. Are you sure you have the correct ALDL port? How are you confirming that the PCM is OBD2? Bryan Herter definitely knows the difference between OBD 1+2 since he gets to charge more for the OBD2 stuff. ;)
Also, are you using an aftermarket throttle body or stock? I'm running a 58mm BBK that had to be modified to allow the IAC to function at idle and the feed hole is still a little small, but we're working on it.........
One other thing, check your coupler between the MAF and throttle body for rips, tears, or leaks especially under the hose clamp that secures it to the throttle body. Any un-metered air will cause some serious idle fluctuations as well as intermittant steady-state cruise problems.
