IMRC Solenoid Damage After LT's

[Ramblinman65]

Not sure if this has been discussed in another thread, but please kindly point me in that direction if so.

Recently had my SW 1 7/8 LT's installed on my PP GT 6spd. Had it dyno tuned (made 406rwhp ) but now I'm pulling codes P2004 and P2011. Something to do with Intake Manifold Runner Control Circuit. Had a misfire at one point. Car runs but stutters slightly. I'm thinking the IMRC connection is damaged as a DiablotSport forum mentioned a guy having same problem on his 15 GT where installer didn't unplug the IMRC before jacking up the motor and damaged the IMRC Solenoid. Took it to Ford and that's what they said it was. Went ahead and ordered the gaskets and solenoid to be fixed by my tuner to see if that fixes it. Anyone else had a similar problem after LT install? Been a week since I ordered the solenoid so hopefully it doesn't take forever as I'm curious if this solves the problem. Thanks for any input.

How much is the solenoid?? And the solenoid doesn't go upward with the motor when it's jacked up???

Paying around $100 for gaskets and solenoid. :frusty:

What is this and where is it located?

I can't quite answer this exactly, and someone please correct me if I'm wrong as I'm no mechanic, but as I understand and from what I've learned the intake manifold must be removed to access it. I think they're somewhere in intake manifold between the upper intake plenum and lower manifold. They're butterfly-like flaps that open or close at or above 3k rpms to manage turbulence. Since my solenoid is damaged I believe it is causing the flaps to stay open which is what is causing my stuttering and misfire.

I don't see how this would be caused from jacking engine from oil pan!

This is what I read that got me in this mindset of the jacking up the motor to install longtubes. https://forum.diablosport.com/viewtopic.php?f=44&t=53035 I could have a separate issue entirely, just using what resources I have to try and figure out what is going on.

Please let me know what happens!! My car never threw codes but spuddered all the time and when I went to get a tune it only put down 386 with long tubes intake and exhaust. Tuned the car only made 406 just like yours. I returned the car back to stock because I couldn't find the issue

I would like to see a pic of where this is....

I recall this happening to another member of this forum. He jacked the engine too high up and damaged the solenoid.

The solenoid and vacuum actuator are the pieces on the back of the intake manifold right by the firewall (have to remove engine cover to see it) the proximity of these components in relation to the firewall makes them prone to damage if the engine is jacked up. Exact height for damage, no clue, but you dont have to separate the manifold to replace these components, the small vacuum line on the inside bend of the intake tract leads under the intake manifold to the back of the motor where you will see a y connector and 2 vacuum lines going to the solenoid.

Hope this helps.

Damn, I didn't know about this when I did my install, but I only jacked my engine about an inch. Dented the pan very slightly first time as I didn't have my block of wood close enough to the edge of the pan.

Thank you for the detailed explanation. Much appreciated.

Shaun was telling me about your car, I sent him this link to see if it helps.

There was a post on here a while back, when jacking up the motor the wires that connect on the back of the motor or intake by the fire wall were pulled tight and broke the connector. this is probably what happened. maybe I can find it
