Re: Head Replacement!!
*** UPDATE ***
Well, They jumped the gun on the diagnosis. I just picked up my H3 today. They did not have to replace the head. Once they scanned the computer it showed no signs of needing the head replaced.
They did a reprogram of the powertrain control module with latest calibration and replaced the sensor for traction control.
I hope that this is good news for me and no head replacement in my future. Knock on wood!!
