Of course I forgot 2 more things that started at the same time as all of this.
- stalling out while driving, usually only at low rpm.
- cruise control stopped working
Keep in mind that all of this started without me moving anything under the hood except oil and coolant caps for a year.
I don't know how to find a fuel leak. That's the first thing I wanted to look for but the auto shop said they didn't have anything for that. I have some putty I can seal it with if I can find it. What about the loud noises? It's never made this much noise before, like there's a gaping hole or crack somewhere but nowhere that I can see. I'll clean it up and see if anything manifests. Thanks again.
