So ive been looking all over the internet and even emailed raw brokerage to find answers. My problem started 2 days ago. My wideband (innovative lc1) got stuck on 22.4. So i re-calibrate it and its back to normal for that day. Next day cars running fine and randomly the readings go erratic along with my idle and loss of power not electronics but turbo isnt spooling no bov. I pull over and its going from 7.9 to 22.4 and trying to die. i limp it home. Next day i try to start it it wont start. itll turn over but wont start. I ve been looking around and i keep finding a lot of things to fix such as mafs (still wont start even with it out and when it was running once i pulled it out the car would die instantly) ecu fried, a coil pack s*** itself, or ive seen people saying it could be a coolant temp sensor. So hopefully here i can get more concrete answers.

Also checked the codes and i'm getting a 55 so everything's fine according to the ecu. Fuel pressure gauge is at 40 psi so im getting fuel. Any thoughts guys?

fouled plugs because it ran with a blown ic pipe and you've tried to start it like that.

try cleaning it with the maf cleaner you can buy. Might just be dirty.

Well i already swapped in the n60. Was a breeze lol. But #6 injector isnt spraying so ill run some injector cleaner through it. If that fails its off to get them cleaned.
