When ever I drive my car over 100km/h (60mph) my tach jumps around between 3 and 4.5k… the engine doesn’t sound any different nor does my speed change (though the speedometer kind of bounces sometimes) when this happens.
I don’t get any misfiring so I don’t think this http://g2ic.com/tegtips/engine/10.html is the issue… anyone have any ideas on what I can do? Im at work right now pondering the issue
