Hey all,
I changed my spark plugs to NGK iridium (.8 gap), and am finding that at idle and down low the car seems lumpy.. Almost like I have put a new cam in it, also I have noticed the exhaust note seems to have more definition (for lack of a better word)..
The car seems to be running well, its just down low and off boost it feels weird.
Any suggetsions as to what this could be.. Is it just the new plugs (the old ones where very old a shitty), maybe a timing thing??
Cheers
