Cylinder problems?

art leong · 03-28-2013, 02:29 PM

I thought I wounded a head gasket recently. Number 2 cylinder had the plug come out quite dark, not sooty but dark.
When I got home I did a leakdown test and all cylinders looked good ( from 3% to7% number 2 was 5%). I pulled the fuel rail and put pressure to it to see if the injector was dripping, Looked fine.
I'm going to swap injectors to see if the problem travels.
Anybody got any other Ideas?
The car is of by .015 or more in the short times leaving real lazy, and down a better than 3 tenths in the quarter.
Here's a picture of the plugs. After 2 runs and loading it up.
