I have a 2008 impala v6 3.5 flexfuel. engine sputter like it has a misfire

And your point? No worries , if they even reply , then maybe we could actually be of some help , but as you'll find , about 90% don't bother. I agree with your response , just don't assume their mechanical 'savvy' when they are asking about a misfire , and we don't know if they know where to start. Know what I mean? Once you've seen enough posts with people listing hundreds of dollars in parts , and THEN they ask a question , .....Ya know??My end goal IS to save them money!
