I have a 1977 280z with running issues. What's wrong is that when I start the car, it cranks over fine and will start fine but after the initial start it will immediately bog down and either die or run on like 3-4 cylinders :sick: It helps tons when I push the AFM in about 25% of the way, but If I let it go on its own the car sputters and bogs down again or dies. With the AFM pushed on full (the top cover is off) I can slowly push the car up to a fairly high rpm, 5000 or so, but I can't seem to do quick revs or the car will backfire even with it in all the way. Here are some of the things I've replaced: -New cap and plug wires (with relatively new plugs; they're NGK, don't worry) -New fuel filter -New seals for the fuel injectors -New fuel regulator -New coil Here are some things I've done: -Cleaned the fuel lines -Set the timing -Tested the fuel pump (It works and puts out about 36 pounds of pressure between the new filter and the rail) -Tried a different ECU and a different AFM (Both came with the car and both give the same results) -I did do a compression test awhile ago and everything was fine, and I should be able to do another compression test tomorrow afternoon -I checked to see if the injectors work by taking them fully out of the car starting it and see them all work correctly -I did check the voltage of the clips going to each of the fuel injectors and those all work fine -I checked the points in the ECU that go to both the AFM and the fuel injectors both also came out fine -I checked the electrics in the AFM itself and everything seems fine (it's also possible to hear the fuel pump working when the AFM is puched in slightly) If anyone has an idea of what might be going on please reply, I feel like by now everything should be working at least sort of correctly. I'm at the point where digging into my pocket and sending it to a mechanics shop or buying a Megasquirt system would be better than wasting anymore time on it. Would maybe replacing the whole AFM do me any good? Could it be a bad sensor sending a bad signal to the ECU? I appreciate anyone's input!
