That's normal, current is flowing to power up some modules, usually a few Amps.

Yes.

Do you have a 100 Gs, to cover legal expenses, and do you have two more plaintiffs? The rear seal failures is well known. Not a defect, but due to neglected maintenance. GM published bulletins on how to prevent/clean the carbon build up. You should sue the government for mandating insane CAFE...

Lesson Learned, don't replace parts based on codes. These modern cars require expertise, and diag tools to properly diagnose.

Did you perform a throttle relearn after replacing TB and AP? Did you use OEM parts?

Yes. E30 offers much benefits in terms of carbon build up. Less than that like E10/E15. Keep in mind that ethanol has 30% less energy compared to straight gas, so you will see a drop in fuel efficiency. Experiment with different high octane, non ethanol fuels.

Being a parts changer for 30 years is meaningless. Have you actually data logged engine performance, efficiency, examine combustion chamber deposits when running various octane fuels. My 12 year old car actively monitors fuel volatility, timing, engine knock, alcohol percentage, exhaust temps...

That's just a pre-filter. AEM has a high flow, re-useable filter. Doesn't require oil. Made by K & N.

Absolutely, both Top Tier and using the highest octane has many benefits in the long term. On my FB forum I have posted testing results. GMC Terrain Chevy Equinox Care & Maintenance

I would be proactive and replace the vacuum pump. If they fail, can cause major damage. I've seen them fail at 50-70k. Use premium oil, change every 3k, ignore Oil Life Monitor. Use premium Top Tier approved fuel.

When I was in Colorado and worked at Cheyenne Mountain AFB, owners rear windows would sometimes shatter. Caused by sudden pressure fluctuations, high winds, weather anomalies. We would park at the base of a mountain range where temps change quickly. Cars now have vents to outside to prevent...

Just saw your post, not on this forum that much, join my forum on FB.. https://www.facebook.com/share/wBzJ9pbx9xfWkw23/?mibextid=JOZb8W

We have a service manual for the second Generation. https://www.facebook.com/share/wBzJ9pbx9xfWkw23/?mibextid=JOZb8W

Used car dealer? Did they even take it for a test drive or inspect it.

Did they use an OEM CAT and O2 sensors. After market are known to fail. Is your engine burning oil? Excess fuel, long term misfire can melt the converter. Leaks can also set the code.
