I did a quick search and found this.

I suggest searching on this forum a little and read up on it a little to decide if it is the way you want to go. It has been several years since I did it, so I cannot remember for sure which wire it is. Read this link and look around a little using the search in 3rd gen section to find more.

 

You might try unhooking the battery for about an hour so the the PCM can relearn it's adaptive memory. It's free and worth a shot.

 

Disconnect#10 pin. The PCV is screwed into the back side of the intake by the TB/Left side. You should also consider changing the Map sensor in the front as they get dirty too, and for 03 require a tab mod on the intake but the instruction come with the sensor (approx $30 dealer/cheaper than Napa).
With 3.92's you should fly. Use Tow/Haul in town and try starting in 2nd gear and then shift when you need too it will have more punch. I love my 03.

 

I looked at the computer and there is 2 computers. One is on the passenger fender and one is on the passenger firewall. It says the one on the firewall is the one u cut but I seen a yellow wire with green stripe on the computer on the fender. I just want to confirm that it's the one on the firewall and not the one on the fender. Does anyone know for sure?

 

And what is the tab mod you were talking about

 

The 03 has a PCM and TCM. later ones incorporated both into one unit.
