Please I was wodering if you could spare me a bit of your time. I have a 1982 280ZX Non Turbo. It runs ok but once it gets to operating temperature of say 130 or approximately 15 to 20 minutes or running, it chokes and shutters and dies, If you let it cool for a couple of minutes, you can always start it up again but this time it will die in about 7 to 10 minutes since it is already warm. The car does not overheat. I have changed the following, 1. Brand new ignition module 2. Brand new pickup coil 3. Brand new plug wires 3. Brand new distributor cap and rotor. 4. Tested with a new fuel pump but same effect so I returned the new pump. 5.Tested with another coil from another Z but same effect. 3. Changed all injector plugs. 4. Cleaned all contacts I can see in engine bay. I am currently confused and at my wits end. No body has been able to help. Your time and any input you may have will be invaluable.
