Get a scan done , these are drive by wire (no throttle cable) there are many problems with this system, also known problems are inlet manifold vacuum leaks and faulty TPI sensors, get the scan done first.

Also they are prone to faulty coil packs, they use coil over plug technology, and the coils are individual for each cylinder, i have often had to replace all six coils as they are a constant problem as well.
