Erratic idle
Last time I've driven Cobra I've laid on throttle then all of sudden it died, I've restarted it and limped home and just parked it. Part of fuel hose was leaking (rubber started splitting) I've figured it was low fuel pressure and I replaced it. Now it doesn't die on me but idles anywhere from 900-2000K on cold startup, doesn't die. Once it starts warming up it still does it from 900-1200K (normal idle on it is ~900)
I was wondering what went wrong, boost leak somewhere or? I've parked it for winter but would like to fix it later so I can drive it next summer.
