'05 Tahoe 5.3 / P0171 / Rough Idle / Misses
I checked the IAT & ECT, but only after it was already warm. I'll check it cold later today, thank you! I did clean the MAF, but I don't have a known working one to sub out. And no exhaust leaks.- Bwaite27

No. In fact, on Saturday, I plugged my computer back in and it's showing both codes now. 171 is the "system too lean" code, and 455 is the "evap system, large leak" code. I think they're related. I'm thinking the evap leak is big enough that it's letting too much air into the intake and throwing...- Bwaite27

Thanks a lot! That's some good info there. I actually did check some of that, other things I wasn't aware of, so I'll do some digging. Much obliged!- Bwaite27

'05 Tahoe 5.3 / P0171 / Rough Idle / Misses
I did all this myself, so it would be me having to re-check all that work. I'm really not interested in going through all that again. Lol And yeah, I'm aware they're different, but it just seemed odd that one disappeared for a while during the time that the other was showing up. I've been...- Bwaite27

Thanks for the response! So the 171 code I've had since I got the truck about 2 yrs ago. I replaced the 2 upper O2 sensors (OEM parts) before I even put it on the road, it didn't change anything. Then it randomly started telling me to "TIGHTEN FUEL CAP" on the dash, so I replaced that. It kept...- Bwaite27

'05 Tahoe 5.3 / P0171 / Rough Idle / Misses
Long story short (as possible) - I recently replaced the fuel pump/ sending unit, all fuel lines and nearly all evap lines because of a P0455 code. Dash kept telling me to tighten fuel cap, so I will likely be replacing the gas cap and fuel fill neck as well, cuz at this point, why not?! I also...- Bwaite27

Anyone know where to get these style cell phone mounts?
Found this. Looks like the same one. They have several styles for different vehicles. Just make sure you find the right one. I'm not sure the link will bring you directly to this one. I had to scroll over a few images to find this one. Hope this helps. Good luck! I didn't realize they even made... -

Was in Florida for 5 years. West Palm. Moved back to NY a year ago. I'm not very tech savvy, but I know a mechanic or two who might have such a thing. Will definitely ask about it. Thank you -

No heat or A/C
Hey y'all. New here. Just inherited my grandfather's '05 Tahoe. Having some trouble getting any temperature change whatsoever from any of the vents. I've done some troubleshooting. It has manual controls (not auto) for driver/passenger sides. The blower works on all speeds. The position selector...
