I have a 03 max se and i bought it in 05 with 76,000 miles on it. When i got the car it was in great great shape. motor, tranny and everything worked perfext xpect for this weird water sound. Everytime i hit the gas it sounds like water or bubbles. LOL. It happens from time to time. Ive done fuel injections cleaners, and i always use 93.. Theres not one time where i put anything cheaper than 93. ive tried water removers, gas treatment, and all the things. Ive takin it to my mechanic as well as autozone and no codes are coming up. I want this noise gone... Any suggestions what it can be or how can i fix this crap
