Just wanted to say thanks for this thread. Google search led me here and when I popped the hood the intake boot was torn.

Unacceptable on a vehicle that's only a few years old.
My 1977 VW Rabbit CIS Fuel Injection intake boots are literally 42 years old... Build date is 10/76. I've owned the car since early 1981 or late 1980 when I bought it for salvage with over 1/4 million miles. While I did swap a nearly new 84 GTI 1.8L engine from a burned down car into the chassis to replace the badly worn out 1.6L. 250K ws a lot of miles in 1980... Lots of things that should've lasted didn't last very long but it hasn't needed new intake boots.

Hay I have a 2016 Chevy impala and the check engine is on. I had it check and it is pulling code po442, po174, and po496 and I have no clue what these are. Can someone help me on this. It is hard to get it started after putting gas in and has died on me when sitting at lights or about to die on me. Please someone help me on this. Thank you

Have you checked the air intake hose (the rubber-like thing between the air filter box and the throttle body)? I've been reading a lot of reports of that host basically falling apart on the 9th gens - even on newer, low-milage vehciles. Check that for tears, etc. And I completely agree with @hatzie here - it's ridiculous that this is even an issue for such a simple part that has been used forever on every car...

The P0442 and PO496 are Evaporative Emission Control codes. Based on the fact that it is hard to start after fueling it is most likely the Canister Purge Solenoid. The P0174 is probably a result of the other two codes. Take it to the dealer, this should fall under the Emissions Warranty.

My bad - I mistakenly thought that the poster was talking about the same codes that the OP was talking about (since they posted in this thread), which is why I mentioned the air intake boot (since that is what solved the OP's issue). Upon looking closer, I see that two of the three codes they are talking about are completely different than the codes that this thread is about. :-)

That being said, I do still recommend that all 9th gen owners check their air intake boot periodically, just so they can identify that issue before it actually becomes a problem (and maybe even get it replaced under warranty while the warrnty is still good). It's obvious that there is an issue with the material GM used for the air intake boot.

Please come back and post when you do figure out the issue - that is *so* beneficial to other forum members, but unfortunately, most of the time, it doens't seem to happen.
