i swapped out my coil pack and the car runs again! but now.....

have some extreme sound kinda like an exhaust like coming from the cat area....gets really loud with the more pressure i put on the gas....also white smoke was coming out of the exhaust and last night my car was pouring smoke from everywhere at a drive though but drives fine idk i feel a low misfire....assuming its the plugs and wires not gapped and wires are original.

thoughts?

also some wierd clicking sound wen i relief pressure off the gas pedal it sounds like a broken axle but today it did it wen it didnt even move.

 

maybe blown head gasket or u are low on oil and thats your rods knocking trying to let u know they are about to break your block in half lol

 

take it to the exhaust shop

 

idk about that i just had it redlined adn spinnin 3rds alll the way down the highway i think my block would have snapped then if that was the case....ill check add some oil though i just replaced adn welded the oil leak on the pan. and no likes.. my oil temp stays around 60*C and my temp goes up to full temp then will drop to about half
