Well it would have been a good idea to disconnect the battery for the swap as you know. What computer did you replace? Each computer has different characteristics and different tables. Also did you add a MAP sensor to the new setup? Heres a link that details the swap that you might find useful. I'm not sure if this was a simple computer swap or a mass air conversion

Good luck

I set it to 40psi vacuum off. Your car is a '90 right. Do you have a MAP sensor under the hood on the firewall? If I recall right it was only the later year mass air cars that had this sensor. If you installed a 93 cobra computer chances are this computer needs a signal from this sensor. It's been awhile since I've done this but thats what I recall.
