You might want to share a little more information on what year your car is. I assume a 3.2 Carrera. If that is the case the first culprit is the DME relay. It is a little black box the size of a matchbox under the drivers seat. They are known to go bad and cost around 25$ to replace.

The DME itself is the computer (silver box) also located under the drivers seat. Find someone with a Carrera and swap your DME into that car. That is the easiest test to verify whether that is your issue.

The boxes can be bench-tested and rebuld. Contact me if you are interested.
