Now have 140k miles without any major problems. Started car recently and a engine noise started out of nowhere. Noise almost sound like Diesel engine running. No engine lights or codes showing up. A local mechanic diagnosed noise as a cracked part inside of intake manifold. Ended up taking in to Toyota dealership and they diagnosed as same. Toyota dealer ordered and installed new intake manifold and cleaned throttle body($780) but it didn't fix the problem. Here is a run down of what's going on. (1)Noise is heard in cabin of car thru firewall but not outside of car or engine compartment , (2)when sitting still and press accelerator to take off the car hesitates / shutters before taking off, (3)starting of engine is effected as well. Rough starts, usually doesn't start on first try. Toyota mechanic also ran fuel pressure test and it was within their spec but a little high on pressure. Anybody else had any of these issues.
