Naw it would blow up...I said boom but nothing actually went boom...just a little hiccup then limp mode and I let of the accelerator immediately.

But since everything is back up and running I made a bunch of 150 pulls back to back to back just to stress the system out and heat up the engine but everything is running top notch without any faults and because of my oil coolers can't get the heat up over 230

i saw the video of a guy testing the mosfets and he gets a reading putting the negative and postive wires on any combination on the mosfet so im confused as to why i only get a reading with the negative on the backside with the positive touching the strips coming out the other end.

sorry i know its kind of confusing but i dont have too much time to take a picture and show you what i did so hopefully someone understands what im talking about and can comment...otherwise ill explain and take some pictures later of what im talking about.

Thanks for the help guys.
Did you end up using the Harbor Freight multimeter to test these? I have the same one and I'm getting the exact same thing you describe above. I only get readings one way, not like in the video where the guy tests them both ways.

if you get continuity between any pins per mosfet, it is bad. Also please use a rework station and flux, kapton tape or foil around the work area. 650f / low air should make quick work of removing / replacing them.

I'm completely clueless about anything electrical honestly haha. I won't be doing it myself, but I just wanted to verify which ones were bad so I could replace the coil/plugs for that cylinder. With the cheap harbor freight multimeter, I am getting numbers on the screen on all 6 mosfets, which I know can't be right. The codes show that it is bank 2 that is having the issue, so the mosfets for 1,2, & 3 should be fine, but yet they still give me the same numbers as 4,5, & 6 do haha. I'm at work now but I will look more into it when I get home later.
