2JZGTE GS300 Mass Air Flow Circuit
Greetings Everyone,
I've got my swap in everything connected. I have a rev limit of around 3500RPM I'm guessing seeing as I don't have my tach working yet, but I have two codes 21 for O2 Sensor, and 31 for Mass Air Flow Circuit. Does anyone have any insight on what is causing this? I bought a 2nd MAF connected it with no success still same code 31. The new MAF was said to be tested verified working. Searched another forum guy had the rev limit issue, bought a new MAF issue solved.
Thanks in advance!
