P0442 error code on 2004 Rainier V8. by snoking

Our Rainier is starting to repeatly get a P0442 error. Onstar twice said check the fuel cap for being tight. I reset the error with my code reader, but a couple months later I get it again. I checked the fill pipe seat and cleaned the gasket on the cap. Anyone else having this issue currently?

We have a 2004 and it does not use oil. Maybe it has something to do with the displacement on demand V8. The only thing our V8 uses is a lot of gas! It has never seen a service station it did not like or want to stop at.
 
My wife however loves it! It will turn on a dime and give her change.

Replace the fuel cap. I think it is a chronic problem with these SUVs that the fuel caps won't hold the required pressure after about 5 years.

If replacing the cap doesn't work, it could be a problem with the fill tube on the tank. I don't have the paperwork in front of me, but there was a service recall for road salt corrosion on the fuel tank fill tube (only if the vehicle was purchased in the "salt belt").

make sure after you put in fuel you turn the gas cap at least 3 clicks if that doesnt cure the problem it is probably time for a new fuel filler car (they do go bad)

Is this a good brake pad deal? by pepito51

Thinking about having my Envoy with 78,000 mi. checked for new brake pads. At previous tire rotations I've been told they are "OK". Gmgoodwrench has a special this month (after $25 rebate) of $74.95. This includes installation of ACDelco DuraStop ceramic front brake pads. If rotors have to be turned, they told me that is about $80.00 extra. Four questions:
1) How good are the DuraStop ceramic pads?. Is that the same as or as good as OEM?
2) Why is it only "front brake pads"? Is it uncommon to have to do the rears, or do they last longer?
3) Does this sound like a good deal?
4) For future info, how long do rotors generally last before they, too, have to be replaced?
Thanks!

2. Most of the stopping power with a disc brake vehicle come from the front brakes. The rear discs typically last twice as long or longer.
 
3. Don't know. Get a quote from a reliable independent shop (not Midas).
 
4. At 78K miles, if you need brake pads you should have the rotors turned. Milling the rotors removes imperfections in the surface of rotor, which will allow your new pads to stop better and last longer. Unless you go to Midas or you have rotor warpage that requires a lot of milling to flatten, you should be able to have rotors turned at least twice without replacement. There is some minimum rotor thickness that must be maintained for safety and the mechanic will tell you when you have reached that point. The problem with Midas is that they machine the heck out of the rotors the first time so you have to have them replaced the second time. And there will be a second time because they use cheap pads that wear out quickly. It is a game for them and the sucker line (yeah, I fell for it years ago) is lifetime pad replacement.

TROOTH AVOID MIDAS!
got ripped into $900 of service.
had i driven 80 miles to my old mechanic it woulda been about $200-$300.
 
i only go to midas for the $19.99 oil change adn tire rotation and then nod my head when they attempt to tell me what's wrong.

Funny, my 2002 Envoy XL with 63K miles also needs new pads...the brakes make strange "whoosh" sound instead of the more expected grinding sound.
 
Where did you get the GM goodwrench deal from, is there a coupon for it?
