I have the battery on my bench re-conditioning and the LP regulator AISAN unit torn apart on my bench ATM. Tomorrow when I get the rebuild parts in I will put everything back together and test the idle bypass solenoid as well as take a look at that trim injector and post my results. Do you think I am safe soaking that trim injector in diesel fuel to clean it? That's what I hear the industry standard method of cleaning injectors is, but that's for gas injectors...not sure if there is much of a difference though.
