Sounds like you have a misfire. Get the codes first to find out which cylinder is the culprit---unless you haven't changed the spark plugs at 100K miles, which will cause a misfire. You should also change the plug wires too if you haven,t unless you have seperate coil packs. When you take out the spark plugs check the gap- their probably worn wide open. Give this a shot.
