'99 stalls- help me?

History- 99 starting stalling at start up when cold, would run when you held gas down. Per advice on forum, checked battery-okay, replaced IAC valve- seemed to fix problem for a couple days. Now I got a check engine light- code was P1294 ( Injector High side bank 2 open- Idle speed not reached). Listened to injectors w/ stethoscope, all sounded fine. Car idles , runs okay. I reset light by disconnecting battery. But now it's back to stalling intermitently. I would appreciate any direction to take. I will post results. Isn't it funny how computer can make it easy to diagnose, yet hard to fix. I guess with the high cost of dealership work we are forced to do what the mechanics do, "start replacing parts".

check for any vacuum leaks, check for any loose
connections at the iac. check if throttle plates are binding...
