ive got a 07 tacoma. only thing done is the lift tires and a k&n. i did the spark plugs the other day and i know i gapped them correctly and tightened them. the spark plugs are densos from toyota. and i checked just to make sure the part number was correct.
i get home from work today and its making a faint tapping sound.sounds mainly on the driverside. if i rev it to about 1300 rpms just at a sit still i can hear it pretty distinctly. anyone have any ideas? almost like a valve tap. but i dont see that with 42,xxx miles. i appreciate the help in advanced.
