I bought my 2008 Cobalt SS about a month ago and noticed it had the drop in filter installed. Assuming it was a K&N I bought the K&N filter recharge kit and followed the instructions to clean and oil my filter. After reinstalling the filter I feel like my car is a bit sluggish. Has anyone experienced this before with the drop in filter?

Thanks

 

probably too much oil on the filter and is coating the maf sensor

 

If you think you may have over-oiled the filter, just get some MAF sensor cleaner from Autozone and spray the MAF sensor with that. You can wrap the K&N filter in newspaper for a few hours to help absorb excess oil.

 

Exactly^^^

 

Thanks all. Unfortunately after I posted this yesterday my check engine light came on Should I perform the above before taking it in?

 

Yes.
