thanks for the info... My battery looks old as hell... But I dont have any idea when it was last replaced... I will hook up a charger to it today and run a 2 amp trickle charge and see if that doesnt help anything... As for the pinging noise I got... I cant get it to come back... I even went down to like 4 MPH in 2nd and pushed the gas down again and it didnt do it... Maybe it was just a different car arround me that did it? or Maybe just a gaurd underneath the car was rattleing?
