It sounds like a problem I had when the connection to my mass air meter was full of crud. I took it off, disconected the battery, brushed the connections with a small brass brush on the battery and the wiring connector. I sprayed all of it to clean it off with wd-40 and hooked it all back up. That seemed to do the trick. One other thing you might want to do is to clean the throat on the intake manifold where the accelarator switch is located. There are three bolts that have to be taken off and you can save the gasket if you're careful. Take some carb cleaner and clean all the carbon that has built up around the opening. Pay special attention to two tiny orifices that are in the throat. Blow them out or clean them out, the generally have filled with crud that's been drawn up from the crankcase. Also make sure the accelarator switch just clicks on when you turn it. I had a very high idle when I adjusted it and that fixed it. I you have a "Haynes" manual or equivilent it will give you the exact steps for adjusting the accelarator switch. I hope these work.
