2006 Tribeca H6, 215k miles, Fixed my Cylinder 1 misfire by soldering IC608 as shown in the above post. First checked pin to board solder joint, then traced to this IC that grounds each injector. Please don't bake your entire board. There's also a video on youtube where Black Horse Repairs completely removes the chip to clean and install with new solder. Again, very risky, just use a fine solder tip and reflow only the pins of this chip. Post something after this if anyone even still works on these cars!
