Computer needs to be reflashed at the dealer.
You will probably have to have the car flat-beded to the dealer to have the computer reflashed with the stock program. If you just take the computer out and to the dealer make sure you have your complete VIN # with you. The dealer will probably charge you $75.00 to reflash it.

I hope that you get the car reflashed cheaper than that. If you have a good relationship with your local dealer. But call then and see if they will do the reflash with PCM out

I did the same exact thing with a Hyper Tech Programmer also. I freaked out. The car would barely run when I started it, then died and would not start, I was freaked out at the time. I pulled the battery cables and hooked them back up after about 20 minutes. Thank God it started. No codes, ran fine. Don't know if this will work for you, I'd try it first.
