HELP!....car makes noise when gas pedal step.." pre-ignition"
basically..when you step on the gas from a stand still point or when ur driving roughly 50km or so n let go gas completly and then step on it again.. you hear a rattling noise...kinda sounds like a loose screw...coming from mufflar or underneath the car who knows... sounds like a screw is junmping around underneath somewhere...
was told from town n country for me to put my original mufflar back on and they will possibly take a look.. till then.. im stuck with that gay sounds... the guy told me.. something bout pre ignition..have no idea what it is.. any clue?anyone? |

So you have an aftermarket exhaust? Take a look underneath to see if any of the hangers broke off....that could be causing the rattling....
