Installed with my tune in place. No worries.

Hey FJR06, I did a little research on doing the seafoam on my engine. I saw a few videos and there's conflicting information out there. I was wondering how you performed this treatment.

I put either a whole can into a full gas tank and a whole can into the intake manifold through the brake booster vacuum line. Follow directions on can. Warm engine, put seafoam in booster line intake, shot off for however long the instructions say. Start and rev for awhile somewhere where you can handle a serious amount of smoke. Smoke will stop after a while. Drive it around a bit. Done. Pour super carefully into the vacuum line or you will stall the vehicle (just restart it). If you have a friend, they can hold revs at around 1500. Makes it a little easier. I never put anything in my oil, so I don't recommend that.

The attached images of how to find and feed the vacuum line and how I set up a tube a funnel for application.

Yes, plenty of discussion about whether or not to seafoam. I chose to do it in order to clear out my manifold the best I could before putting on the catch can and a new TB. My TB was too far gone to clean. I tried. The carbon was burnt onto it. I tried all the tricks I found on this forum. Couldn't get it to budge. See attached. Old TB and new. Also a view inside the dirty manifold. The seafoam did a pretty good job. If anyone knows how to comment on/between photos, please let me know. These are my first pics.

Awesome! Thanks for the write up FJR06. This seems like a cheap thing I can do this weekend. It'll also give me the chance to see what kind of shape the throttle body is in. Right now my 2005 WK kind of rumbles around a bit when I'm at a stop, so I'll have to check on that here soon. I read through my Chilton manual on possible culprits so I plan on checking for vacuum leaks while I'm under the hood.
