Paul,
Are the wiring connectors for those valves still in the same place? I was going to reccommend that he order three of those large resistors from RJM to put across the connectors to keep the check engine light off. I've done it to mine and they work fine. I just shortened the leads and soldered some mini blades to them. Plugged them in and taped them up. No codes after I did that.
Rich,
My truck was running fine until the PCM started messing up. I've also removed the EGR and the smog pump. Got rid of quite a bit of engine bay clutter.
