Re: High revving on startup--ED
well they should rev up to about 1500 for start.. then settle to around 900.. then gradually return to base idle as they warm up.
Controlled by the water temp sensor initially, once that threshold is reached it then moves to the air temp sensor and adjusts accordingly.
The comp works out the best idle for cold running, then once that is met it adjusts the mixture and timing based on the air temp sensors plus the rest.
