Yep, sounds right. My reason for removing the solenoid had to do with tuning my car on HP Tuners. It didn't matter to me about the smell. I was only trying to give the OP a reason for his fumes. It's not a good idea to leave the solenoid disconnected, but it sure helps with fueling AFR stability. I'm sure there a way in HPT to turn it off, but I wanted to be sure so I plugged it temporarily.
