Engine Performance problem
2006 Honda Civic 4 cyl Front Wheel Drive Automatic 67000K miles

Since last week, I can feel I was driving at a speed of around 60-70 km. but somehow the speedometer only moves between 40-50 km. This happened after I put a bottle of fuel injection cleaner along with a full tank of gas. Can u tell me if there is a defect on the speed sensor ? OR the fuel injection cleaner has caused the problem which will go away when I fill a next tank of gas?

ALSO, when I cold start each morning and back out from my garage, I press the brake and heard a light metal pressing noise (sometimes on the left front brake and sometimes at the rear brakes). the noise will go away after running for a distance. My mechanic checked all the brakes and found nothing wrong. He said most Honda Civic have these problem and quite normal.
