its best not 2 drive the vehicle unless need 2. if u need 2 drive it then baby it so it doesnt get 2 the stage where it starts pinging. also with pinging or detonation it is when the air and fuel ignite b4 the spark ignites and if bad enough can try 2 move the piston in the oposite direction and after a while weaken the conrod and worst cum 2 worst the conrod snap and end up through the block.
