Abnormal combustion, more commonly known as knock or detonation, has been the limiting factor in internal combustion engine power generation since the discovery of the otto cycle itself. Not only will you see a smoothing of rough idle and knock regardless of the conditions, but you will also experience significant cost savings with this product. This causes a sharp, sudden rise in cylinder pressure which subjects engine internals—pistons, rings, bearings, gaskets, etc. So, to make sure we're talking about the same thing, it's a light knocking noise, not the normal injector or engine noise. The vacuum advance should give it about 10-15 degrees when connected, causing a leaner mixture at idle and cruise untill you move the throttle plates and mechanical comes in to play. My car is making loud knocking noises at idle. so far no irregular virbration of the engine yet. Its noticable most when i leave it in lets say 3rd gear (autostick) while driving slow and i accelerate without dropping a gear , it will ping ,then stop as soon as the rpm starts going up. But if another internal circuit goes bad, the engine will. Engine spark plugs are responsible for igniting an engine's air-fuel mixture, a process that creates engine power. What does pinging in your engine at idle, loss of power and poor gas milage mean? I have a 1999 Dodge Ram 1500 4x4 with the 5. An engine designed when 102-octane high test was at almost every fuel station in the country being forced to run on today's gas means that ping has become an all too common companion, and what.
