The new headlights are definitely a couple inches thicker / deeper.

Quickly zip tied one of the catch cans on just to see if it actually does anything since even after 150,000 miles when I checked my throttle body it was still pretty darn clean... I'll check it at the next oil change or so and see what if anything it has caught.

Then finished the flex fuel sensor plumbing.
Went to wire it and got the harness all ready to go and then realized I forgot to buy the dang pin to put on the wire. So those should show up this week.

Finally put in a tank of e85 after weeks of running regular or premium, and my goodness what a difference. It really hates regular, pulls a lot of timing.
Such a dog off of the line until maybe 20 or 30 miles an hour, and then anything over 5,500 RPM it does the same thing you could feel it lay over.
91 however, it's pretty good nearly all the time, you could tell a slight difference to e85.
It's definitely happiest on corn though. That added cooling I think makes a big difference. Because it doesn't really matter how hot the ambient air is, it feels like it pulls pretty good all the time.

every since I swapped out my interior lights with leds, they only turn on when I use the dimmer knob. like if you push any of the map lights, they are super dim
For some reason some BCMs do that if they don’t sense enough resistance. I was surprised mine worked. My map lights in my 03 would not work with LEDs

There shouldn't be anything on that side for the can to catch. That's the side where clean air from the intake tube is sucked into the passenger valve cover. The problem side is where the oily air leaves the driver side rocker cover (port near the firewall) and goes into the top center of the intake manifold, well behind the throttle body.

Totally forgot about that one. ‍♂️
Thanks... Sometimes I get a little too eager and don't do research with things I'm not fully versed on still.
Another good reason I only get a zip tied it in place. Hahaha
