Well the car ran ok for about 50 miles, then it started stuttering at part throttle between 2k-3k rpm every 20 seconds or so, which became more frequent and now it's affecting the idle too. Trouble codes are P0300 random misfires and P0172 rich bank 1. My latest idle datalog (
https://datazap.me/u/atk800/log-1545...data=3-7-23-24) has a very high MAF reading (I had just cleaned the MAF though, maybe I needed to give it a few more minutes to dry out).
The first ~400 miles were trouble free with a little idle learning, so I know it can run good when everything is in order. Could I have fouled the O2 sensor while it was running too rich earlier? I've cleaned the MAF at least 10 times with the spray cleaner while I was chasing my tail earlier with the short coupler, could it be ruined now?
