I purchased a 1976 Datsun 280z in mid summer that had been sitting for 3 years. I flushed out all the old gas, flushed out the radiator, bought a new battery, put new gas, put injectors from my previous running 1978 280z [RIP :tapemouth] and she finally had fired up. So i try taking her for a spin and she starts choking on me. I look at all the tubing and notice some are a little old so I have them replaced. I fired her up and still would choke. After about a week I have it towed to Mike's Z Shop in Whittier, Ca. They work on it for 2 weeks and get it to run better but it STILL chokes. They put new spark plugs and a different airflow meter. I just got home from Whittier with it going no more than 50 on the freeway because of the choking PLEASE HELP thank you in advance
