I am looking for a detailed procedure to set the idle for AJ6 1986 engine, starting with throttle butterfly gap, tps check, etc, etc. Actual idle is 1500 rpm with engine cold and 750 when warm. When cold petrol smell inside car during first 15‘ drive (running rich?). When warm hesitation when accelerating from below 1500 rpm. Recent MOT with CO at 1,5. ECU is checked with AJ6 Engineering. Hope someone may help!
