I am getting this weird stumble when I accelerate hard, so I guess I better start by making sure I don't have any boost leaks.

Before starting this fun game, I am buying throttle body shaft seals ont he assumption that mine are original and will need replacing anyway. Is there anything else I ought to buy while I am at it? Some [EXPLETIVE DELETED] sense would be good but the sellers are all out.

 

Thats a good start along with perhaps some injector seals. Most of the other stuff is basically just pesky couplers that could use some retightening of clamps or possibly need to be re positioned.

Honestly, you wont know until you test it and its not hard to do nor does it take much time so hook it up and see if it holds pressure and go from there.

 

test it first before spending any money... unless you just like to have extra parts like i do...
if thats the case... buy away!

 

I tend to squirrel away parts that I don't need yet. Especially because my Evo is a DD and I live in the Great Evo Parts Desert.
