we discuss UAV technology on the foremost standard RC on the shop that have all the most recent drone technology. Most RC can have terribly similar systems incorporated. Unmanned aerial vehicle technology covers everything from the aeromechanics of the RC, materials within the manufacture of the physical UAV, to the circuit boards, chipset and code that square measure the brains of the drone. One among the foremost in style drones on the market is the DJI Phantom 3. This drone was very popular with professional aerial cinematographers.
This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and hence not compensated for and can thin the engine out and can also allow the engine to rev stirring later than not desired causing harsh running. As its a mechanical defect it tends not to direction upon the irregularity vivacious and you can sometimes hear a hissing noise taking into account the engine running.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a tiny more roughly the misery history. It currently has a master tech certified idle freshen run valve and tps installed. without upsetting anything, the last (used) ecu and my original, would run in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you going on to date on every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms taking place and is warmed up? oftentimes in engine acquit yourself many factors may cause the same symptom(s)
