00 accord problems
 

I have a 2000 accord ex 3.0 and have two problems I need help with. I have a p0740 and it said my solenoid was open and I don't know if I get the A,B or both. And the other thing is sometimes when I try to start my car it will stall out. Right before it stalls if i press the gas and hold it at 2k for a minute it runs fine. Are these related or not?
