Issues with white smoke after spark plug change
 

Hello all, sorry about the title, I ended up figuring out the smoke.

I just changed the spark plugs on my 13 FRS at 88k miles. I recently went FI and have been having misfires over about 5 psi, so I figured I would change them out.

I should note that I am on basemap tune for the SBD 500x kit, and have the car has been running rich since I re flashed (with Openflash through Shiv). After telling shiv that I had misfires, I sent him some logs and he said he had difficulty seeing why it was happening.

Everything went well, but I did notice that the DI ECU was missing the bolt on the bottom. From what I read, that bolt is required for grounding purposes. I replaced the bolt and started it up. So far, I have gotten the P0300 code multiple times when getting over 5 psi boost, and the P0303 and P0301 codes off along with it.

Any help is greatly appreciated.

How does your LTFT and STFT look? If it's running rich I'd imagine you have a leak somewhere.
