Check engine light came on when my 2002 Chevy Malibu LS began to idle really rough. I took it to Autozone and it threw a code for a bad fuel injector on my 5th cylinder. I was wondering where the fuel injectors are located in my V6 3.1L engine. It's front wheel drive if that helps. Also if you could tell me how to replace it that would be great too! Thanks for your help.

 

The AZ clerk could tell a particular "bad fuel injector" with the OBD code reader alone? Man, those guys are getting better and better (I hope you realize I'm making a facetious remark here). Based on what you're asking, I recommend taking it in for service. It may or may not actually be the fuel injector itself and it can get expensive if you attempt the repair yourself.
