'95 LX 4.6 -This is driving me nuts. Started with a check engine light, pulled the codes and got 17X; left bank lean/right bank lean. Changed the fuel filter,ran slightly better but cold start symptoms remain.Pinging (lean) under hard throttle. Where do I go from here? I wouldn't expect both 02 sensors to go bad at the same time. Are there any common intake leaks these motors are known for? Help me out guys, I'm a 351C Holly double-pumper kinda guy. This is my wifes car and man oh man, you know the deal!
