07, 2.4. Code will be the same regardless. Not sure why this matters? The questions has already been answered anyway. I was just stating, it has gotten worse since December.

Because TSB 08-06-04-001B for P1174 applies for the 2.4l engine but not the 2.2l, and only in model years 06 and 07. Glad you had your questions answered.

Good to know. Thanks!

Which misfire code did you get for cylinder 2, P0302?. I only ask because misfire codes usually have to do with ignition so that doesn't necessarily indicate a failing injector. It could be that but it also could be a faulty spark plug or wire, a faulty coil, a faulty oxygen sensor, a burned exhaust valve, a faulty catalytic converter, poor compression, or even a defective computer.

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.

Yeah, after I typed that, I realized that I hadn't considered the other code (P1174).

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.
