Be more specific about it ran like crap. Did it go into reduced engine power? Did it just feel like it wasn't getting fuel? Would it not go over 2000rpm?

My first thought is that you are experiencing the injector harness issue. Where the #2 and #7 injector harnesses are not making a good connection. This is a known issue on the 2005.

Does it try to die on you when you are trying to get to 2000 rpm's or does it just sound like it is going to blow apart?

How many miles on it?

Really sounds like the injector harness. You can check the harness at the alternator bracket. One of the issues is that the alternator bracket rubs through the harness causing it to short out. Inspect the wires for any rub throughs. If it is rubbed through you can tape it back up and be back on your way. Also check the harness at the #2 injector. Make sure it is plugged in all the way. You can do a search on here for the ice pick fix. You can try that to keep the connection good. If you take it to the shop there is a TSB on the injector harness issue. They will replace it at no charge if you are under 50K miles on the clock. If not then you are looking at around $500 or so if that is the issue.
