Re: 01 Check Engine Light On

First thing, there are (4) 02 sensors on your blazer. Second thing is you need to take the truck to any Auto Zone and have the check engine code's read. They will do it for free. Write down in order from first to last any and all code's and post them back here in order for anyone to really help you...
