I'd start by fitting a set of new spark plugs and maybe plug wires too. It might also improve your gas mileage. I'm assuming that the 2000 engine doesn't have coil over plug ignition. If it does that makes it more expensive to change the coil packs. Obviously there can be other causes but you need workshop resources to do a full investigation.
