I have a 03 Maxima and im getting this silly liquid sound when i press the gas pedal... I have always used 93 and i flush the radiator. I removed all air from the radiator.. Well i least i think i did it right. i put the temp on high for about 10 minutes while accelerating on 2000 rpms for 6 minutes.. I saw lots of air come out but the sound still exist.. Help please... am i missing something...
The sound only exist when i give it gas.
