i had a sound systm put in my car (250 watt amp and a 12 inch sub) and the car frequently dies now just by turning on the lights or rolling the widows down. i unhooked the amp wire and it still does this. anyone know the deal? Also my car has an inoperative metering oil pump. i read an article that says these are not properly set up for the rx7 and a way to make the car run smoother, more efficient, and longer is to take the pump off and plug the drive pad into the injection ports and mix 2 stroke oil into the gas(i ouce for every gallon of gas). anyone want to comment?

 

Generally the 2 stroke oil is more like 4oz for every 12 gallon fillup. As for the other stuff I have no idea.
