I have been having problems with engine misfires, shaking etc. I replaced the "engine brain" computer and the rough running stopped, but now my speedometer seems to be registering at twice the actual speed and the only other guage (fuel) seems to be wrong as well. Can I do anything to correct this or will I just have to live with it?
