Here is one for ya
79 f150 400 4 speed LWB, starts very easy, idles great, but here is the kicker, when the engine is cold to just warm, or it has not been running very long. When I am driving it and turn a RIGHT hand corner it spits and sputters like it not getting gas, it doesn't matter if gas tank is full or empty. It only does it when turning right, does not do it going strait. As soon as engine is warm to normal range it stops doing it. What in the world could it be? It is really funny only does it going right, maybe I will just to all left turns.
I would start by checking down by the back of the right front tire, and the front of the left front tire for any wires or anything hanging down that could get messed with by the tire. Start there and let me know if you need any other help. I have two of the exact same trucks that I rebuild, but never heard of that.
