Okay I drove my car to Omaha to visit a friend. It's been freakin cold here in the midwest so I figure that may be why. The tach accels fine till about 3k then starts wobbling back and forth and only get weirder as the vtec engages. decel is the same way only it wobbles all the way till 25-3k and then is ok. Have I knocked something loose or is it because it's cold or is it because the car is just gettin old? Please help! it's got 121k miles but it is in near perfect condition and I take care of it like it was brand new every day.
