so when i wind up my motor on the autobahn from like a very slow roll or dead stop i notice that my tach is moving in a strange manner. it seems like it stops very briefly or staggers on its way up. i dont hear anything strange with the motor or feel anything strange, so i am wondering if the tach lead is bad or the tach itself. my blazer had the same issue too, but that thing had over 100,000 miles on it. any ideas?
