1975 Nissan 280Z 6 cyl Two Wheel Drive Manual 120000 miles
Once the vehicle reaches normal operating temperature the car becomes prone to dying. It will instantly restart, but will die as soon as it is started. If I slightly press on the gas while starting the car will start and stay started at about 2,000 RPM. What seems to trigger the dying is a combination of accessory usage and low RPM. For example, if at idle RPM and I begin to turn on the headlights, rear defogger and heater, the car will most likely die if it is warm. I noticed the amp meter goes from -60a to +60a and when first started, it sits at 20-30a, but after warming up it will be at about 3-6a. If an accessory such as a headlight is turned on, it jerks into negative amperage but quickly returns to positive amperage. If I continue turning the lights on and off the car will die assuming it is warm. I believe the problem is the alternator/voltage regulator but would like a second opinion as I've heard EGR, MAF and IAC could cause this problem too.
have the same problem?
