No problem. Start by removing the intake crossover tube above the engine. Then pry up the plastic strip down the center of the cover. There is a front cover too. Then remove the bolts that hold it down. I think the coils come loose when you un do the bolts under the cover. Then the plug wires must come off the plugs too. I haven't done it for a while, but I remember it being pretty easy, no real tricks.
