Thanks to the both of you. I dont have time to work on the car till this weekend, but I know where to start. I'll let you guys know. Chris

you're talking about the air temperature sensor, right? Can the sensor be tested?

Almost fifty and I finally got a Z. I remember seeing my first 240z when I was delivering newspapers on my bicycle. I would drive by the car daily. It was orange, had a wooden steering wheel, and the inside was truly a cockpit. It was on the same lot as the Smoky and the Bandit Trans Am, but it was easy for me to see which car I liked. Datsun... hands down! I recently aquired a 1978 280z. My perceptons form early youth proved true. This car is 30 years old and it is the most fun I have ever had driving an automobile. However, I have been experiencing problems lately. I had the gas tank cleaned and sealed, put a new fuel filter and fuel pressure regulator on, new plugs, wires, coil, fusable links. I am experiencing loss of power after the vehicle runs for a few minutes. Could it be the injectors? After it runs a few minutes the power diminishes. The motor does not appear to be very hot, but the catalitic convertor does alot of pinging like it is hot. Could the catalitic convertor be clogging the system as it heats up? Help! cls
