Hello all. I need some advise. I have a 95 d-90 that has been neglected and garaged for the "pretty days" that is now my daily driver. Things are starting to go wrong in all sorts of ways, but I am getting a handle on it now. Here is my biggest issue. When I let the truck sit at idle it dies. Prior to this it has been hard to start when it is extremely humid out and when it does start it runs like it is missing a cylinder until it really heats up. I pulled the dist cap and hit it with a hair dryer once, and that seamed to help on that issue. Anyway this is what I am getting back on this. My mechanic has told me that he thinks it is stalling because I am putting cheap gas in. He is smelling fuel in the exhaust. He recommended better fuel and berryman's. What say you all, and thanks for the help in advance.
