There is a loud whistling noise coming from the front of my engine, which starts as the engine is warmed up. The sound goes away when I accelerate and returns when I coast. The engine is also idling rough, and I get code 0304 from the computer.

This is a misfire code for No4 cyl, with the noise you are hearing check for a vacuum leak at the intake manifold.

Read the guide below on whistling noises, it will help you figure this out

Got timing belt and water pump, crank and cam seals changed 2 days ago. Car now makes whining sound on acceleration. What could this be? It never made this sound prior to repairs. Car makes whining sound after timing belt, water pump and crank/ cam seal replacement. Did not make noise prior to 90k timing replace
ment.

Cannot take it in until tomorrow as I am wo
rking till after they close. I suspect loose belt. In changing said timing belt a/c had to be discharged and re barges and drive belt taken off. So I'm thinking perhaps something has gone wrong there.
