I detect a hint of sarcasm in your last post. Never the less...I'm glad you found the problem. Often times.....when a condition is intermittent....it is electrical component related. Testarossas benefit from a periodic electrical connection disconnect/reconnect. There are a lot of items in the loop that must function properly for a TR to run "right". Common issues are the circuits for the fuel pumps and cooling fans....you have to watch out for burned connectors at the mother board. Many owners re-wire these circuits and bypass the weak factory connectors at the mother board. All things considered....the Testarossa can be a very reliable car if properly maintained.
