I need some help, I just changed my spark plugs over to the NGK BKR7E's and I followed the DIY forum to a T.

When I started the car up its like a squealing noise is coming from the from of the engine, I can't tell what it is. And it increases as I increase RPM's

There is no codes thrown and no check engine lights. I checked the spark plugs again and they are all torqued to 22ft/lb. The allen key bolts are all tight as well.

The squealing noise wasn't there before I changed the plugs as well, and if anything I feel I have freed up some hp and boost.

Any suggestions??


I bought an extra set of plugs just so I could have them around, should I maybe switch them one at a time and see if the noise goes away?

 

and the noise isnt continuous. It is an oscillating sound.
