Trim the braces. You should be good. Or a 1" BL gives many forms of unanticipated goodness.

I cleaned the air flow sensor with CRC electronic cleaner, the no residue stuff. Hopefully that works.

Did it look dirty? I could visually tell on mine right away that it was dirty. Hopefully that does the trick because we all like quick and easy fixes

It looked like it has some stuff on it. I hope the cleaning took care of it. I wasn't sure if I should touch it or not, so I just blasted it really well with the cleaner, and let it evaporate. I also cleaned out the tube and air box a bit.

That wasn't it. I havent driven the truck all week (don't usually commute with it), so today after detailing it, and taking it to the car wash, I drove around town a bit. As before, stopping for about 30 seconds caused the light to kick on.

I'll try to swing down and see Brian at somepoint this next week.

Looks like Brian found it today.

I used regular old vacuum hose from O-Reily Auto to make all my vacuum connections. That is fine for everything except the PCV system. That hose is not rated for oil, and had "ballooned". Basically, it was no longer making a seal on the PCV valve.

In addition, after clamping down the hose (just a temporary fix, I already have replacement fuel line for the PCV system), the hose started to collapse on itself, which means its likely got a bad PCV as well. So, I picked up a new one upon further consideration, and am going to install both.

The issue was found through Brian's uber sweet computer OBDII stuff, and he read the long term fuel trim at 42%, and short term at 26%. The long term should be no higher than 10%, with not much going on in short term.

Closing the leak down with my fingers, Brian was able to see the LT fall into the teens, and shortterm go negative, which was good.

In addition, I never installed the IAC check valve, which is a must have, so I'm hunting those down. I found the part number, but its an old one, so the good gentlemen at Boulder Toyota are tracking down the new part number, and I should be good to go.

Just adding zip ties to the PCV connection kept the light off all afternoon driving around with plenty of idle time. I'm excited that this looks like a 20 dollar fix.

I'll update in a while after the repairs are made.

NICE!

So it was a vacuum leak basically?

Glad you guys got it sorted. Could have been a lot more tail chasing than that.

Sounds identical to the issue I had with the fuel smell in the cab. Same cause, same fix. I also used an IAC check valve inline with the fuel canister, you might think about that to prevent pressurizing the evap system. Put a hose clamp on the evap line where it attaches to the blower (right next to the brake vacuum line, which not coincidentally has a clamp and check valve as well!).
