I have an 83 280zxt. When it has sat for a few hours it is hard to start. I have to hit the gas to get it to crank. Then it will run very rough for only a few minutes maybe 5 or so and then it goes almost completely away and just has a little misfire. It also backfires when I let out of the gas sometimes and while it is running rough when i first start it it sometimes backfires. I have put new temp sensors in it ( both of them). Does anyone know what it could be?
