Bank 1 system too lean and random misfire

[C0gi30y]

Hello Aveo owners, i will get arounf to posting in the introduction thread at some point. Had i known there was a forum that may have eased alot of the headaches i have been experiencing with this car. So for starters, it's a 2009 Aveo LT.

I have replaced the coilpack and plugs, and the air filter. I have run Seafoam throttlebody cleaner as directed and used their fuel system cleaner.

I have a rough idle and occasional stalling and a constant hiss (vacuum, not blowing) from a very tiny slot in the valve cover near the coilpack which sometimes cause the engine to shudder worse qhen i block it. Everything i have read points to a vacuum system issue, yet can find no materials or pixtures detailing where evrything goes.

What i think may have caused the issue is at some point, the pcv hose popped off the valve cover. The restraining pin is MIA. So before i popped off the valve cover and discover disappointment, i figured a post here may give me a little more direction.

Any additional information anyone needs, just ask. I will be monitoring this thread in the hopes of tech salvation. Thanks!

Welcome to the site C0gi30y.

Sorry to hear of the issues. I'd definitely pop that valve cover off and take a look to see whats going on.
