Tosh Posted June 16, 2007 Share Posted June 16, 2007 I've got a TD04 turbo, 280zx injectors and a spider intake. and I'm running lean at idle? how is this possible I was suspecting to be running pig rich do to the injectors. I just hooked up my narrowband to try and get an "idea" whats going wrong. and it started up and it was at the very last bar before lean. as the engine temp went up it got a little richer. Now I may have a bad FPR I'm gonna replace it tomorrow any other ideas what could be causing this ? Link to comment Share on other sites More sharing options...
Skip Posted June 16, 2007 Share Posted June 16, 2007 A few items come to mind that I would test 1) Make sure the CTS contacts are clean, (you may be "stuck in closed loop") test it's output at the ECU 2) make sure your 02 sensor is not getting old and lazy "......." 3) make sure you have the TPS for the spider wired so the idle switch is connected properly to the harness "........"
