I was wondering if anyone can help? My 92 integra ls has this problem; when i start to go fast, usually around 3500 to 6000 rpm my tach starts jumping around like crazy. Every thing has been replaced, distributer, coil, control unit, spark plugs, wires, fuel filter and now i am stuck any help will do. The car still goes , but a little sluggish and hesitant. Please Help!!
