I have a 78 280Z with an 82 280ZX Turbo drive train. Unfortunately my 82 turbo computer is toast so I have am using the 78 computer with the 78 air flow meter internals and it has been working fine about 70,000 miles. All of a sudden I can't get the car to idle when the temperature is under about 70 degrees. The only temperature sensor hooked up is the air temperature sensor in the air flow meter. Has anyone replaced this sensor? I can't find a source to purchase just the temp sensor?

Any advice would be greatly appreciated.

Thanks,
Randal
