Hi I have a small problem that I would prefer to solve with the right information:
Range rover p38 4.6 HSE 1998 I took apart the plenum chamber to clean the system , I cleaned every thing but did not think the problem that I was getting into :::I cannot find anywhere the Throttle butterfly opening spec .I took out the small Allen screw that is the stop point for the accelerator system and did not check the opening of the butterfly inside ..so now I have a great daub, haw much open should I live open the butterfly ?I have it at this point at o.5 mm difference between the upper one and lower one from the outside 74 mm/up and 74.5mm dawn but then the automatic gear box is not in right range from the throttle potentiometer .Do you have any info on that ?
Saludos cordiales,
