Sounds like the converter is clogged. Remove a precat O2 sensor and see if it will rev past 3500. If so, replace your cat.
The 2.7 is a strong engine with consistent fluid changes, but can’t take any abuse. I’m surprised this one survived all that.
Also, all stop leak is good for is stopping up a small leak in a hose or something, and clogging up a heater core. Glad to see you got it all sorted out.
What’s awesome is, that explained the pull to the left too! It’s gone now!
The front end is totally silent on it, so that is nice. Amazes me that I couldn’t tell when I would shake the wheels, or the guy who aligned it last year couldn’t tell either. That bushing was really bad.
Over last weekend I took a look. Along with a few other things I wasn’t told about, the noise had gotten so bad that it was a constant clunk. So I started feeling around and the UCA was fubar.

The bushing looks fine from the outside. Weird. Ball joint was fine too. Either way, it’s fixed. Thank you for your help.
I’m not ignoring you guys…
I haven’t seen the car since Saturday. 😆 I’ll get under it and figure out whats making the noise soon enough. Thanks for the help everyone!
Strut bearings is what it sounds like to me, but these don’t have any? They’re a coil over like setup and the struts don’t spin.
Ball joints are tight, but I’ll grease them and see if it goes away. I replaced the links at one point too. I’ve been chasing the noise with little success. I normally don’t have an issue finding suspension noises either.
Same issues. They were worse back then actually. Those tensioners at most last 150k most of the time.

The 2.2s (Both Ecotec and Vortec versions) are notorious for failing timing chain tensioners, which can make sounds similar to out of adjustment valves. I would be more apt to think that would be the problem then worn out hydraulic lifters. Just a thought.
