Thanks, Jim! I discovered today that there was another code for the MAP sensor. Fuel pressure is fine, so I guess all that's left is the injectors, huh? Thing is, after I put the MAP sensor in it will sometimes start and run for 20 seconds and then die. If I try to hit the accelerator, it dies immediately! WTH????
