Just in case you may want to see the TSB on the PROM update it's over at the netreg site.

The only issue now is this replacement PROM seems to be NLA. I'm not 100% positive on the NLA, but when I run the P/N nothing comes back. I get the "no such part number" message.

I'd check for vacuum leaks first and you can tell if the PROM was done by hooking up a scanner as it will give the PROM ID# after you verify the VIN #.
