Whenever I start my car on a new day, I observe a kind of vibratory sound through to
the exhaust, steam doesn't come out of the exhaust any longer, the Rev indicator drops below 1 too if I don't throttle after a while when on idle, my mechanic advised I change one of the plug cables described above too which I did, yet no change,

What could be the cause, as I observe this results in poor fuel economy
I use a Toyota matrix 03
