We are fixing a sputtering dying rough idle engine on a 2012 gmc terrain 2.4l 4 cylinder engine. I started by removing the MAF sensor a cleaning it. Then I pulling the spark plugs to see what they looked like. They were grey suggesting we were running lean. Brown is perfect, black is an engine running rich. I then removed the intake manifold to get at the fuel rail to remove the injectors. We then cleaned up the injectors and ran some injector cleaner through the engine to clean up the rest. • Random Miss Fires Cleaning Injectors Equinox, Terrain, Denali • • My other channels: •    / pwnsjones   •    / r3dlin3s   •    / stopdropnrun
