hi Sir, i just have a question, I got a Toyota Camry 08, that is a used car, when I buy it, that only have a problem with air condition , when i turn a/c in high , I felt a little shake, but the engine driving still smooth. So i think that not a big deal cause I just find a car drive for work, After 3 months I bought this car, my car have oil leak, then I just bring my car to repair. finally oil leak had fix, and air condition no more shake when i turn in high, I don't know why, but the shake problem is change to air filter box. The air filter box is shake when I start engine, that is not a normal shake, cause I saw the other car just same my car model Camry 08, air filter box is quite, not have shake like my car, I already asking 2 mechanic about my car problem , they said that is normal thing, (car engine driving still smooth). I just felt uncomfortable about that shake noise sound on air filter box, I don't know what wrong with it. Could you share me your experience ? I looking forward to hearing back from you. thank you!
