    Sounds like sticky valves. You could try adding about half a quart of Marvel Mystery oil to the oil in the engine, running it for about a hundred miles like that and then changing oil. This has been known to correct that sort of problem, and if the problem is still there, then take the vehicle to a mechanic to check for timing belt slippage.
