    93 model replaced the head gaskets.Got her all together ,but she won,t idle after warmup.I replaced the IAC valve and no difference.No vacuum leaks that I know of fuel pump has been replaced.She runs great other than that.Any ideas or advise would be greatly appreciated.

    If this is anything like my '04, it's the computer and not you or your truck. Hear me out, please. If at any time the battery during your rebuild was disconnected, the system is off kilter. After this happened to me, I stopped by a dealership and they reset some kind of a chip to "relearn" any engine changes and/or driving habit changes. No issues ever since. Stalls and a VERY rough idle prior too. I hope this helps.

    I considered this but I just knew it was something small.It,s crazy even though the battery was disconnected .I guess the next time I will just disconnect the ground!!!
