So my Mustang has been rattling here lately, mostly when my foot is on the gas. Tonight was the first night it rattled when idling. I turned my car on and it acted like it was going to bog out and then it started to rattle without my foot on the gas so I put my foot on the break and put it in reverse to back out and it still rattled till I put it in drive and got on the main road. It never gives me any problems driving just the noises, the bogging feeling just started recently too. It hasn't bogged out completely and died though.
