my truck had to sit for a couple of weeks until I could get my transmission fixed. Now it doesn't run right. It backfires or misfires out the exhaust when I let off the gas when I'm going over 40mph. ALso a noticable lack of power. Idles fine. New plugs, all wires connected. Please Help! 1991 318 TBI

It sounds like a possible timing problem, but I could be wrong.
