Replaced Timing belt at 100K miles, after timing belt change, if I
press gas pedal, I can feel something is holding like applying brake,
took back to mechanic and showed it, he said, he just changed timing
belt only, he is good mechanic, he asked me to drive for few days and
see, probably belts are new, it will take sometime.

when I press gas pedal, I can hear some sound like something is
touching, Is this common when change the timing belt, thanks in
advance.
