Need help my h3 is acting up!
Hello everyone, I am having trouble with my 2006 Hummer H3. The H3 idles rough really bad and it sometimes turns off when I get to a red light or a stop sign. I took it to the local GM dealer but they were not able to fix the Hummer. It drives awesome on the freeway but if im in the city it tends to turn off about 1/5 of the time when I come up on a stop. The check engine light comes on and off. But, I was able to get these four codes of the machine. C0240 Powertrain Control Module traction Control Not Allowed. C0268 Class 2 Data Error Reported History. P0017 Timing Misalignment Explanation, Detected the Crank Sensor is not Aligned with Cam Sensor, Probable cause intermittent connection, Failed Crank or Cam Sensor, Engine Mechanical Condition. P0300, Cylinder misfire detected- random cylinders explanation, The powertrain control module monitors the crankshat speed and had detected a misfire condition, proable cause ignition system faul-spark plugs, ignition wires, coil, vacuum leak, injector fault, or low fuel pressure. I had the hummer at the dealer for about 18 days. Im not even sure they did anything to the Hummer honestly, I looked at the spark plugs and they were considereably shorter than i expected. Went and got the original ones and also, put a new filter on it. but, its still acting up. The dealer said it put new sensors on it, but i dont think they did. at this point i would rather do it myself. Can anyone help me?

Search: Battery Terminals/Battery first then Throttle Body Cleaning and MAF Cleaning. Multiple codes can be caused by bad battery terminals or a failing battery. Good Luck

Awesome
So the camshaft position actuator solenoid is the problem? Does this cause the Idle? Just wondering.

That is correct.
#6
X2 on the cam position sensor. If that does not fix it you may have a stretched timing chain.
How many miles on it?
How many miles on it?

It has nearly 149000 miles. Would the Timing chain cost a lot to fix?
#8
yes, unless you do it yourself and it will cost alot of time.
