I did the whole B&G treatment today. 44k, Intake Cleaner (Vacuum Application), Intake Cleaner (Throttle Body Application).

Of course the engine stuttered and made lots of white smoke when doing the vacuum application and just stuttered on the TB application. It also died once when i removed the PCV valve from the intake line. I was actually surprised that i didnt get a CEL. However, when i ran the codes, i did get a 07-01, Multiple Cylinder Misfire. I reset the ECU and drove (hard) around the block. Checked it when i got back and it was not back. I will keep an eye on it, but I am wondering why this didnt trigger a CEL?

Thanks.
