CruiZZZin 78 Posted July 22, 2007 Share Posted July 22, 2007 I have to crank my 78 280z over a dozen times before it finally starts and barely runs at 400 rpm and slowly evens out at 800 rpm. After I let it run really rough and it warms up it gets a little better but when I crank the trottle it revs up but missing at the same time. I checked the timing and it seems to run better at 18-20 degrees instead of 10 degrees (were it should be) for some reason. I have good spark. My injectors are clicking. I pulled the vacuum line off the feul pressure regulator and no feul comes out so I geuss its good. I pulled the plugs and they were carbon fouled. I was also wierd that my idle adjustment screw doesn't affect the rpm very much. How can I rule out the possibility of the problem being my AAR or my TPS? Could it be my mass airflow? PLLEEAASE I need help! Quote Link to comment Share on other sites More sharing options...
