My 2012 does



so checked and my 2011 does too. what a weird thing to change across the line up.

I also looked under it and found this hole. I'm guessing it's where that lock tool goes? if it ever shows up I'll try it haha.

looks like you could just stick a pin in there and tape it off, same effect?

maybe it is round. just have to find the right side, there's a bit of a head on it and I'm guessing a friction ring to hold it in. but yeah, some tape and the right size pin..

here's a list that popped up for special gm tools form otc. better pics of it are done a bit but also check 7297. with all the old pressure posts that pop up. man that would be super simple to spin on a mechanical gauge to check pressure.

I've got enough ls's around me I might get one just to get it lol.

air ride huh. how's it ride? are you lowered?
I'm going back to the stock RPO Z55 autoride suspension. It's not an aftermarket kit, I don't have bags. Not lowered.

Not done yet, but as soon as I am I will let you know how it rides. : ) Still need to do the driver side and put the compressor on.

that is a proper long daily man. our job started at 4am. so left early mornings. he ran the gauntlet, deer in the mornings, I think he was up to about 5 by the time I left and bad drivers on the way home.

I don't have that kinda commut in me.. I'm 9mins from work here and when the alarm goes off at 4am I still struggle haha.

I'm "sahourlary", so traffic fattens my paycheck. I rarely leave the house before 8am, but I also don't get home until near or after dark most days. Bad drivers all day, err' day. Biggest stress of my job. Really, "bad drivers" isn't even accurate. It's inconsiderate, self-absorbed and entitled people that are their shíttiest when others are on "their" roads.

Left the house with the DIC displaying "27 MILES TO EMPTY" to go to the nearest source of E85- a RaceTrac 22 miles away. Grabbed $30 worth which was 11.721 gallons at 2.559/gallon. Went for a steady cruise in the opposite direction, away from town, to avoid traffic lights, etc. to let the fuel composition relearning get its stuff together as quickly and accurately as possible. I don't know if that's even necessary with the physical sensor. But, whatever. Made a U-turn and went home, totaling about 36 miles of mostly cruising after the refueling.

I noted an average of 18 MPG at 70 on my test course home:

That's pretty good MPG if there's any decent amount of Ethanol in this load. I pulled into the shop and realized my RH headlight was out. Popped the hood to get a fuel sample and gave the headlight a slap and it lit up. Collected the sample and saw that the headlight didn't come on when I turned the key on. I removed the air filter box to replace the bulb. Just used a stock one from a spare headlight housing. Cleaned the air filter and reassembled it all. Threw the Autel on it to see what the PCM had the alcohol content at then closed up shop.

Alcohol content is showing 62%:

It's been almost three years to the day that I've been running it with this seal. Actually over three years installed. Looks like it's still holding up 100%:
