04 Cobra 2.76 Eaton
340lph pumps pulse width modulated
Bolt ons
60 lb. Injectors
The car was tuned remotely and runs strong under wot. Tuned to lambda of 0.78 at wot and did all part throttle stuff. Week later I noticed an idle puls .
It happens if I clutch in and go into neutral at any kind of speed (like lazily approaching a light) the rpms dip and go between 750-950. Wideband showing lean pops like it is misfiring. New Iacv, tps, plugs, cam sensor, crank sensor. I cant seem to get it to stop doing this. Definitely embarrassing. Any thoughts all? I also tested vacuum. Reads 21 through the pulsation.
