Engine Performance problem
2001 Chevy Blazer 6 cyl Four Wheel Drive Automatic 109000 miles

I have a code P0101 coming up (among others) when I take vehicle thru inspection, wont pass inspection, just replaced fuel pump and fuel injectors.

Can you tell me what this code means besides the definition on your site? In laymans terms?
