Hi, have just rebuild my 1FZFE and am having an issue with the idle.
It runs okay for a few seconds after cranking, then idle shoots up to 3200, then drops to 2200 and continues going up and down for a few minutes until it just has enough and cuts out.
Have checked the spark plugs, ignition timing, fuel pressure etc. Thinking maybe Idle Air Control Valve but am after thoughts / previous experiences. Thanks.
