Recently bought a 2003 Chevy Malibu. Great car. A couple of days ago it started making a "chirping" sound when in the car and more of a light click when you're outside. It's under the hood but couldn't locate where. Any ideas what it is?

I would check to see if you have spark. If not I would suspect ignition module.

The first thing is to make sure you are not low on transmission fluid. I would expect more a whining noise than a whistling. But the slower shifts may definitely indicate a low fluid level and/or fluid that is long overdue for a drain and refill.

you couldve split/cracked fule line. check where its leaking from carefully

Sounds like the battery is weak. If it is older, replace it. If the module is bad it would'nt start at all.

could be ignition switch but in alot of cases on the newer ones it ends up being the computer.

To clarify - - if the engine cranks the battery and starter are ok.
The alternator does not come into play until the engine is running.
If it cranks but won't start, you have to figure out if you are missing fuel to the injectors or spark to the plugs to proceed.
A mechanic would check that and if there are any trouble codes stored in the computer.

Intake gasket is shot or of it has been replaced it was poor work
These engines are famous for intake gasket issues more so if it has GM dexcool antifreeze. 700-1000 in shop. Find a good back yarder. Parts arround 100. Couple hun for labour

Need to replace the sensor inside the gas tank. I have a 2008 Malibu with the same problem. It was a faulty fuel gauge sensor.

Hello, I read your problem, and a lot of the symptoms you are describing seem like itmis possible, that you have a bad 02 sensor, this is part of your emissions, relating to the cadilac converter, it mostly acts up at lower speeds, like coming to a stop or slowing to make a corner. Sometimes also a bad fuel filter could cause this when rpms are down such as slowing or on corners. That is the two things I would check. Thanks mike

Have the DIS module checked and the coil pack for cyl 3. If either/both of those need replaced, have it done and have the codes cleared. Then see if it clears the others.

You may need a TPS (throttle position sensor) as well.
