So, how about it? Why do I have a second throttle plate that is basically an electronic choke plate in my TE511 throttle body? Why would you choke a FI engine when starting? Also when does this thing move? What tells it to close/open? Temp sensor? Run time? When does it close again? Someone help me out here. It would be much much more effective to just inject more fuel at cold start. Why would you reduce airflow? Is the throttle body too large (46mm?!) and it need more vaccum on startup to pull or draw the air fuel charge in? That makes no sense! Wheres an engineer when you need one?
