I'm tying to figure out why after I accelerate the speedometer and the tachometer rise like they're supposed to, but if I take my foot off the gas and then reapply, if at that given time the tachometer falls between the 1000 and 2000 rpm by the time I give it gas, it sometimes will stick within that range and won't budge unless I slow down even more or I give it alittle bit more gas with a quick step of the gas pedal, then it will bounce up and read the correct rpms. The engine seems not to be affected because the mph keep rising and engine seems to keep revs fine, although when the tach gets stuck there a feint noise when I give it gas until it gets unstuck then it functions fine.
Does the tachometer have its own motor that operates it? because the Noise it makes is like something is getting stuck and trying to free itself. Also reading on the tachometer, receives impulses from different machines in the car, What are the possible causes that my tachometer sticks like this and makes a feint noise. Is there anything in the tachometer mechanism that would make noise? Or is this a warning sign for an underlying issue.
Also I haven't received any codes, I'd figure if it was something serious that had to do with the engine or transmission that it would throw a code.
