ok so every now n then when i take off from a stop or just cruising at about 2300 rpms ill here a rapid rattling noise...it sounds like change but its not...lol..and i know its not a rod knock.....so when im cruising at about 2300 it comes and then goes away...then comes back and then i hit the gas and it goes away...it doesnt happen often...but id say about 5 times a day....cold it be the resinator?! and if so how do i go about either deleting it or repairing it?
