Re: Question about MAF
I don't think it would, long as the screen is before the sensor and not after. Can't imagine why it would be after.Comment

Re: Question about MAF
yea the screen was before. And I drove it with no problem for a month or so. I didn't think it would make a difference but Now I have two codes telling me I'm running to lean.... I'm starting to wonder if it may be a bad PCV valve...2002 Firebird<br /> <a href=\"http://www.cardomain.com/ride/2106142/1\" target=\"_blank\">http://www.cardomain.com/ride/2106142/1</a>Comment

Re: Question about MAF
Removing the MAF screen will cause the AFR to go wacky. So your answer is yes it can cause those codes.sigpic

Re: Question about MAF
a bad PCV valve wont cause the engine to run lean.. it will cause oil consumption thoughComment
