hey guys, i went on vacation last week, left my car sitting in pretty shitty weather for 5 days. when i first started it up, it kinda puttered and hesitated, then it eventually started to idle fine. but when i reved it past about 2500rmps this weird squealing came from what i think was the engine or maybe on of the belts im not sure. i took it around my block and still did the same thing.

please let me know ASAP of what you think this could be

thanks a lot
