Could anyone share average LongTerm FUEL TRIM for 2013 2.4L Equinox, Im up to about 18% on idle with new pistons.
Smoke machines are usually used to find vacuum leaks.
They can also be used for pressure lines or actuators and valves.
I assumed you had used one before.
Google smoke machines for vacuum leaks and you will find a bunch of youtube videos showing how they work.
