08 Almost Total Power Loss

[Kingjustonian]

I have an 08. 242,000 miles. Many miles, I know, but I love this vehicle and I’m at a loss. There’s zero power when accelerating, especially on hills. A sucking sound in front of the drivers side engine compartment. And a popping from the manifold on the passenger side, especially at startup. I tried the carb cleaner vacuum leak test, no results. Any suggestions? I really just need it to run reliably at this point.

Possibly a plugged converter?

That’s my next plan. I have no vacuum leaks. So it’s either the IMRC or a converter. I think.
Thanks for the advice!
