Code 16 & 43 on B18A1 EF

[HackAbuse]

Okay so my engine is intermittently throwing codes 16 and 43 (Fuel Injectors & Fuel Supply System) with the current symptoms.-Excessive Greyish smoke from exhaust
-Engine wont rev past 5k, pops, stutters, and bounces near 5k. (rev limit is 7200)
-The car isnt nearly as fast as it should be.
I compression tested yesterday and came out with 180psi with a 5 psi tolerance on all four cylinders. The valvetrain was replaced 2000 miles ago, along with most of the other internals. The head was also milled, bored and resleeved .02" over during the process.
Anyone have any idea as to what's going on?

i'm having the same problem with the code 43 right now.. might be a faulty FPR

that black/grey smoke is unburned fuel.. i'm guessing the codes are because you're running pretty rich.. not sure though

I would suggest doing a full tune up. (ignition, fuel, etc)
I don't know what your problem is, but it can't hurt to know that it's not something as simple as a clogged injector or something making these problems happen.
