One problem related to engine has been reported for the 2003 Chevrolet Blazer. The most recently reported issues are listed below.
Chevrolet Blazer would rev up and after a year began to run a little hotter than it should for no reason. I had it checked many times. A few months ago I was told it was a bad sensor. Was this a defect from the very beginning. It does not rev up now. Has anyone else had this problem.
