Does not help it still stumbles at low rpms he did the same thing to me and I told him it was wrong and didn't work and then Assured me it's my wiring and to check it agian.
I'm having the same issue, my tuner can seem to figure it out and said he has tuned hundreds of these manifolds and said it's my wiring but mine is the same as everyone else so not sure I'm about to give up and go locked out.
I really appreciate you doing this I've been dealing with this code P2005 for a few weeks now and I missed this post. Had to change the values and no more code and the imrc work perfectly now and do not shut down anymore thanks again.
You should keep the check valve on the imrc, it holds vacuum for when you start the vehicle instead of building it up every time they might not work for a few secs since it's a vacuum reservoir built in.
So after talking to AdrinMAK, they had the same issue as some of use throwing a p2005 all they did was shut down the code. He did write me back and he is right it does not effect the dyno at all but as far as daily driving you notice it under part throttle and you do lose a few mpg, I'm locked...
Mine is throwing the same code as his we have been talking, my imrc are working I can physically see them, after I take the car for a drive they both stop working but no CEL a few mins later it shows up P2005
From the picture a few posts back.
The "brake booster source" is where (needs vacuum) and (brake booster) gets it's vaccum from. The fourth connection in the union is when there is no vacuum and pulls vacuum from the intake tube but has a check valve built in so it's not a vacuum leak. I either...
i have the wiring and vacuum diagram just like raptorgabe and im still throwing a P2005 same code i had when i hooked it up just like the 2017 with both solenoids and vacuum lines now i went back to the 2018 setup and same thing. I already ordered lockouts 2 mpg is not worth it anymore until...
So I just spliced my blue connectors together and wired how your picture is and I'm still throwing a P2005 stumbling and everything I'm just about to say eff it and go with lockouts.
I Installed a 2018 ported manifold on today, I wired it the way pictured but I soldered them instead of crimping but I used the 2017 manifold runner solenoids and routed it like 2015-17. No codes as of yet but I feel As though it will because kinda stumbles on really low rpms like the runners...
