If you are in sixth gear at an extremely low rpm keeping the gas steady on a flat road but the minute you press on the gas pedal it shudders. I am curious as to where the vibrations originates? Is it clutch slippage or is there a more vulnerable weak link along the drivetrain considering the fact that at that low of an rpm the engine would not be able to overcome the static friction of the clutch with the available torque at that low of an rpm? And no I do not do this I am just curious as to how it all comes to be? Since our cars are fuel injected I wouldnt think that for a split second the engine got too rich? Or could i be wrong?

 

i think its becasuse the spark plugs develop carbon on them because the engine cannot burn the fuel properly or completely...or something like that...Dont hold me to it thought
