That is a cylinder 1 misfire. Check compression in that cylinder, check coil... If you already replaced the plugs, check to make sure it is getting a good hot blue snapping spark to that cylinder and make sure the injector is getting power.

Just to add to this one i have seen some of the newer ions have low compression on a cylinder causing a dead hole.Also as far as checking the injector circuit best to use a noid light it shoukd flash while cranking and not stay on solid.

That is what I was thinking too, Saturntech. Thanks for the input.
