Yes, you may want to try the C/K forum instead. They will be much better suited to answer your questions there.

Did you check to see if there is any slack in the throttle cable!!?? And also pull your intake hose off and see if the butterfly blade on the TB is caked in gunk or really if the little hole is caked. You'll see what im talking about if its there!! Also do you have an aftermarket intake hose at all?? If so check your MAF sensor to make sure it didnt get any oils on it from the new filter!! hope this helps, Let me know
