What do I see, do you have a problem with your pointer failed before the tuning? If so, be sure, the ignition time is well, in the event that the spark plugs is very czech to check that all the cylinders are burning well, in case some is failing the spark plug wires to see if it has a good spark or that none is damaged if they are well assured that the injectors have washed them if they work correctly I think that you are talking about a deeper failure of the interior of the interior. Alla suffered heating, some flamed valve, or that does not have good compression, etc. and the torque of those screws is 4 steps the first of 30 lbs-fie, the second 40 lbs foot, the third is a quarter back and the room is added another quarter and the foothold mode is in the form of a snail I hope this information serves you.
