yes.... the amount of vacuum being pulled thru the "metered orifice" on the other side may not be enough to over come the "fresh air intake" at the resonator. I probably need to cap the barb...
Thanks for the hints. As suggested, removing the brake vac line helped get better leverage and hand access... plus I was then able to see what I was up against in terms of the length of the...
Moving the brake booster vacuum hose out of the way gives you a bit more room to work and is easy to do.
The plastic barb is, hopefully, tougher than you think. I say hopefully because you never...
On my 2008 TB 4.2l with 240kkm plus, I thought that perhaps its a good time to pay some attention the the PCV path.... especially since it appears that perhaps the system is not working "well"...
OK, update.
I tested the continuity between the female slots 71 & 72 on the ECM connector and the female slots on the knock sensor harness connector. Both had continuity and no resistance. I had...
Actually, I think this code (and related sister code) means that the system will not being doing its job as the system disregards the output from the sensor and thus there is NO compensation done...
Here's the schematic for the knock sensors. You'll want to check the wires for sensor #2.
Be sure to check resistance/continuity from the sensor wires to the PCM and also to ground on both...

Have you actually looked at your misfire counts?
There are likely other things associated with actual firing issues that would show up if you look at fuel trims.
why did you pull the radio? Maybe there was some "back feeding" happening for voltages and when its gone, so is the "back feeding".... maybe check fuses.
I think you have an electrical issue... potentially powering of the PCM. The "check engine" should be coming on. As tjbaker57 has stated, check powering and grounds going to the pcm.... maybe...
