Nah, its an 05, I'm sure theres no warranty left.
This weekend I pulled off the 07 intake manifold and put the 05 manifold on the engine in case it was cracked or there were any other problems that might be causing a vacuum leak. Again, no dice. I'm really running out of things to replace!
It's usually the very last thing that you replace that fixes the problem... :P That's what happened in most cases when we were fixing a problem with the jet...

because once the problem is fixed you don't replace anything else

I finally called up the local garage. Their "drive ability guy" is on vacation atm. Looks like I'll get it in late next week or so. I'm almost out of ideas.
One thing I did remember though. When I reset the codes on the engine, it stays in closed loop for a little while. After a while it kicks back into open loop. I guess in open loop mode it must not be misfiring because it runs fine. I should redo my tests with the codes reset to see what happens.
I can guess and say you need to perform a crankcase position sensor relearn procedure, your dumping some fuel for some reason, or you cat is slightly clogged causing a back up..
but its probably something more simple.
I did loosen the bolts before the CAT and fired it up to see how it effected things, it revved even slower than normal, so I don't think its the CAT.
It would be great if it was something simple that I'm just overlooking.
If you have any other ideas I'm all ears.
Put two cans of NOS energy drink into the engine oil.......

I finally took the car to a local garage yesterday. They diagnosed it this morning. Apparently, it needs a crankshaft relearn procedure done on it. They borrowed a tool from another local shop, but couldn't get it to work. They suggested I take it to a dealer to take care of this.
