Cracked Intake Manifolds

[Tlauc1999]

I didn’t expect any problems with a new intake manifold. The IMRCs are completely new as well as the intake of course. If I still had a problem I’d be in trouble

The guy who did my PP3 install said no lean codes usually means the manifold isn’t cracked….. just getting lots of different info from different people

Mine was cracked and had no codes. I found it while doing a log and it was adding 30% fuel. I had the fuel trims set at 2% or less and then this popped up. So I knew it wasn't the tune.
