P1174 indicates fuel trim cylinder balance malfunction. This means that your cylinder-to-cylinder air to fuel ratio is not balanced properly. Usually caused by a faulty heated oxygen sensor located on the exhaust or a simple vacuum leak. It will not harm your vehicle but it will lower your fuel mileage and the engine light will remain on until the issue is fixed, which will fail an emissions test for some states. This may be repaired free under your emissions warranty. Check with your dealer.
