P1174
#14
Came back today, for the first time since December. It threw the P1174, and a misfire code on cylinder 2. Looks like injector two may be failing. It is smoking a little on cold start up as well, white smoke that smells like pure gasoline. Going through a rough couple of weeks here lately.

Yeah I know, the other situations. But the two codes at once would lead me to indicate that 1) it has to do with the injector or 2) the injector acting up its self could have caused the plug to lean foul or fuel foul.

So almost 2 years later, this code came back on the way home the other night (6 hour drive). I erased it, and it has yet to come back. It did not show any signs of running poorly either. TSB shows injectors, but I find it hard to believe, because of the long interval.

Do to the age of the post I'll post a new thread, but I get the same thing. Very intermittently it will throw code P1174, and ONLY when it's been driven at highway speeds twice in the same day. I typically use the same stretch of highway every Saturday and when I'm on my way home I can predict within a mile of when it will come on. When I drive it locally and after 4 or 5 starts the light goes back off.

See ChevyMgr post above. Common problem with many 2007's and the 2.4 ltr. engine.
Also do a search regarding the window switches and the gas fill location. Many discussions on each of these. So your complaint is not original.
