1982 dodge ramcharger starts and doesnt run unless reved.?

Hey guys I am in desperate times for help, my ramcharger will turn over and run for about 10 seconds unless you rev it this being said it won't run without a little push. could this be the timing spark plug wires. one of my spark plugs isnt torqued could that be it, um I have 87 unleaded which is the right fuel. I also wanted to know if the extra quart of oil the previous owner put in could be the reason, but I really am not sure. I would so appreciate some help. I know my way around a car so this is just one of those problems you can't fix right away. Thanks
