This is an odd recent-occurrence, but now, when getting-off the freeway and coming to my first Stop, the truck will generally "die" on me as I approach low RPMs / a Stop... I've consequently had to start it back-up in Neutral (while slow rolling) but in doing so, it seems to be stuck in some-sort-of state where I need to be accelerating or it will die... However IF I have the luxury of being at a Red light (or heavy traffic), I can put it in Park, rev the RPMs and it seems to return to a "normal" state, once-again properly dropping RPMs without stalling...
I have indeed recently installed a Fuel Cutoff solenoid which I suspect may be contributing to (the source) of my problems, though I am having trouble figuring-out how it could malfunction(?)...
Any suggestions would be greatly appreciated, as I will most likely disable and go back to dieseling in the meantime...
Thank youz!...
