Strange miss - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I can't work on my truck until tomorrow but I thought I'd get some ideas from you all before I start. Installed an Edelbrock manifold & 1406 a few months ago and truck has run fine until a couple days ago. At idle, in park, there may be a slight hint of a miss but I am not certain. Revved up in park or neutral there is no miss. Drop it in gear and there is a noticeable miss. At highway speeds or under acceleration I do not notice a miss. Lastly, after driving it a few miles it will diesel when I kill it--this started the same day as the miss. So, what do you think? Plugs, Plug wires, vacuum, timing, combo of these or something else. Thanks.
