Default anyone have a little time to help this Sun

So I'm looking for a helping hand... this morning I drove my 09 sti to workout no issue. At lunch went to run an errand. Before leaving home I decided to check my P/S inlet connection o-ring, as I have been getting some moan. I read on iwsti that the inlet can end up leaking/letting air in. So I pulled the oring and measured it, so I could buy a new one. Put everything back together but forgot to bleed out the air. So on startup my P/S reservoir overflowed, but more importantly out of the blue the engine idled terribly and got smoke out the tailpipe.

I exchanged msgs with Travis and he thinks I have a loose vac connection. Anyway I'm looking for someone with experience with troubleshooting this kind of issue. Give me a holler if you have ideas or live in EV or looking to do something constructive! Thanks. I am thinking:

* vac leak
* bad injector (pulled all spark plugs and did comp check, #3 I smelled gas when I pulled the spark plug) -- compression check showed all good
* bad coilpack

Spark plugs all looked ok, black carbon but not heavy/wet/chunky. Travis has me tuned pretty conservative.

I'm in Chandler.

Ok this has been the most frustrating witch hunt in my limited weekend mechanic experience.

After performing the following:

* comp test
* leak down test
* borescope cyl
* coil pack swap
* spark plug swap
* noid light test inj wiring to inj
* replace injectors (was going to do anyway)
* other misc tinkering I can't remember

it was after the 1st time I removed and swapped coils on #4/#2 that I must have not gotten the coil boot onto the plug (trapped between the plug and cavity wall instead). Once I got that corrected in runs fine!

Still doesn't explain why after servicing my P/S that I got the smoke and misfires, it's not like the coil can come loose. I am guessing that the #4 inj was going bad anyway, and then for whatever reason it failed upon startup after the P/S service. The coil misassembly was just a coincidence.

It's funny I called Travis and he pretty much nailed it.

Note to self: do not buy used cheap-o brand injectors off nasioc ever again. Even after getting them flow checked it was the wrong choice.

It's amazing how much better the car runs with the ID1000's isnt it?

But, in all your troubleshooting, we got to find out the engine broke in nicely

I'm glad i could help
