There's no way that's related.I have the black lung! after I received the following trouble code one day and had starting issues;
PO191Ful Rail
S CIR RNG PER ---Fuel Rail Pressure Sensor Circuit Range/Performance
Not sure if it is directly related but I thought I'd share.
I'm going to go against the grain here and say I don't see much of an issue here with this intake "breathing"... There's been no failures (yet), and the only "rocking" I can see the injectors doing would be on the bottom o-ring, which is not pressurized by fuel, and at no risk for fire or leak.
I can see how there would be some cause for concern, but until I actually see a failure, or real problem from it, I'm not too worried about it.
