Hi Scotty, this is a shot in the dark and ile keep it short and sharp. I have a 200 KM (im in australia) 95 ford falcon station wagon with dual LPG and ULP in line 6, 4.0 litre. Cold start in the morning is great, starting the car after a day of working, the car turns over for a good 3 - 4 sometimes 5 seconds and then once it starts it takes time to build up pressure in the cylinders. Ive taken it to a shop and paid someone 500 bucks just to tell me that he doesnt know whats wrong with it. Btw, big fan of the youtube channel, really honest good old school mechanic advice, love your work mate.
Well unfortunately LPG is not popular in the United States on vehicles at all so I have no experience with working on them you're going to have to find a guy who's an expert with those things cuz they completely different than normal gasoline powered vehicles good luck
