hi guys, im driving a civic ek. Recently when i revved my car into vtec (regardless of any gears), the front end of my car will start to wobble. Went to my mechanic and nth was found wrong with my undercarriage n axles. Suspected to be the wheels and tires, so i went to change to a new set of tires n have them balanced and the prob is still tere. No wobbling at high speed cruising, it will only start when i hit vtec and wobbles all the way to redline. N funny thing was i hit vtec (started to wobble) on 2nd gear n revved it to 8k rpm, the speedo needle will malfunction n went back to the 0mph position, den i shifted up to 3rd (wobbling stopped as outside vtec zone) and cruise normally at ard 55mph, after abt 3sec, the speedo needle will suddenly jump back to the speed (55mph) that i was crusising at. Dunno if the wobbling had caused the speedo needle to behave like that. Any kind guys can help me on this? Thks..
