i have a 2003 toyota camry v6 3.0. i just had the water pump and the timing belt changed. after the replacement the car doesnt seem to idle as it used to. now it is below the 1000rpm when i turn the car on at park position at about 500rpm. when i am stopped it has a little kick to it, the engine block is vibrating, ive never seen it vibrate like that. also when i turn the car on it shut off a few times as soon as it turned on. the way i see it, it isnt idling the way it should be. at stop lights when i used to be stopped and i start to let go of the brake it would have a somewhat strong roll then it does now. please give me some advice. ive been reading online, and some people say it could be the throttle body need cleaning, if so how would i do that? and some say the car needs to relearn the idle because the battery was disconnected or what not.

thanks

Hope the timing belt was installed correctly.

Let the PCM relearn by running the engine at idle with all electrical components turned off and until the cooling fans come on.
Turn A/C on and run for another 5 minutes and check if the idling is stable.
