did you go from dpfi to mpfi?

[spoolinhx]

yes i did

It might have something to do with the wiring of the dizzy, so back track your wiring there. I dont remember what need to be switch but here

this might help

[Formally...]

Did you use your original dpfi engine harness or did you use a mpfi harness? Also, you have to add two wires from the dizzy to the ecu if you used the dpfi. Here are couple of links that may help. Finally you cannot use a mpfi harness in a dpfi car unless you change the harness that goes from the shock tower to the ecu.
