I assume that you have already checked the ignition system. You replaced the MAP and fuel pump and most likely have checked the fuel pressure at idle. When mine start acting up at idle, I start looking for a bad vacuum line or connector. The most vexing one was a connector which was partially cracked and it wasn't until I pulled on it and it came apart that the Dx was complete. The tell tale sign was that half of the cracked surface was dirty and the newly cracked half was clean. Strange but true. Good Luck
