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!

I had number 1 missfire.. I used an led light, you can see it blink, looking closely. Hot to battery, negative to injector wire. (Led polarity matters)Tested with working injector, then number 1, was no blinky Two things.. adding power should not and will not open injector, adding ground would.. but don't, you're shorting ecm. Instead of buying new ecm, solder board where injector wire pin is on it.. They wires all have black sheathing in last plug, easy to find.. Much cheaper, fixed as soon as you melt cold solder joint, slit second. Update it was actually this IC. SOLDER all connections.
