cyl four running very lean (burned plug)

[bremertontalon]

My talon is running very lean on cyl four (farthest drivers side) burned the ground strap off the plug. All other cyls work fine. I took the injector from cyl two and tried in on cyl four to test the injector, two worked fine but four still worked like crap, so I used my noid lights im getting an injector pulse I am assuming its on time but I have no way of testing. The only mods to the car are headers and a 16g turbo but boost is stock timing stock everyhing is stock. any one have any ideas?

I figuired it out, no compression at all in cyl 4
