Torque Loss on Testarossa 1990

I've noticed that the torque is gone from the car, and it is rough starting when cold. Once warmede up, it operates fine, starts fine. It revs through the entire range of RPM's fine too,
It's just that when I put my foot down on the pedal, there isn't the quick spark advance giving the car torque. It is more like a steady cruiser style increase in power through the gears.
Anybody have ideas on what would cause this please? I was thinking bad ECU, but not sure.

It's hard to say without more diagnosis - but here are some generic things to try......

Does this problem occur when cold and when warm? If this happened suddenly, the usual suspect would be ingition related - like a bad coil or coil lead wire. Verify both cylinder banks are getting spark. If okay then check all of the vacuum hoses, make sure they are all in good condition and connected. Unplug, replug ALL of the electrical connections in the engine bay. At the mother board in the trunk, remove the white connectors at the bottom of the board and look for burnt connectors - particularly the connections for the fuel pumps.

Does the car lack "torque" when cold AND when warm....or just when cold? Please do some checks and let us know what happens.....
