Thank you for the replies. I've photographed the AFM connector and also drew a diagram of what I did. When I say its running poorly, its barely staying running and smoking out of the air intake. Very weak idle, and when I give it a bit of throttle, it barely will rev up then die. Thanks for making me photograph the AFM, once I drew this diagram I know what wires I crossed, but I do not know the consequences yet. I wired connector pin 34 to the wire that was supposed to get connector pin 33, so pin 34 and 33 were swapped, wired backwards. The other wires on the connector 1 and 2 that were supposed to go to pins 32 and 25 were not connected to anything this AFM only has 4 pins. It was idling a bit rich around 1500 rpms before I changed the pigtail on the afm. It was leaning out at high rpms when boosting. It ran at this baseline right before I changed the AFM pigtail, this was the first electrics part I changed trying to fix a rich running condition. I was planning to start the car and test it after cleaning or replacing each part so I would know what, if anything, fixed it. Thanks again! Pics below

Hi there, 1982 280zx Turbo Car was running rich at idle, then it seem to switch to running lean at high rpms once it built boost. I was going through the engine bay and replacing connectors, they had started to degrade, some were missing clips and some had started cracking, I also was cleaning connections starting with improving the electrical connections to see if that cleared up my issues. I was doing one connection at a time, and then testing the car so I would know what fixed my issue, if anything. First item I rewired was the AFM Connector. Fired the car up and it ran terrible and was smoking. I shut it off and started to look. I realized that I had wired the AFM backwards. So if - was = to an open pin on the connector, and | was where a connector was an occupied pin, I wired it |||-|--, instead of --|-|||. I rewired it properly and restarted and it continued to run very poorly and die. I have checked the ECU where I though a resistor maybe had blown I had replaced the Fusible Links with a maxi fuse set up and those checked out. I ran through the FSM Tests for the AFM and it has checked out fine. Im not sure where something else could have went wrong. I am imaging the engine ran very lean when I had it hooked up backward and that explains the smoke out of the turbo and Intake so I could have done serious engine damage. I need some ideas of where to go from here. Is there something else inline with the AFM that could have been effected by my mistake? I havent tested fuel yet, but that wasnt a problem just minutes before I miswired the AFM. I have ordered a Fuel Pressure Gauge. Any help would be appreciated. Thanks! Kendall
