A few ways to do this. you can use carburetor cleaner and spry a little in to the tube that hooks up to the PCV. or remove the Throttle body and give it a complete soaking in carburetor solvent. you will most likely need a small rod to brake up any deposits that are not cleaned out. GM also makes a great top end cleaner that you can use. runs around 20 bucks for the bottle, but it works fantastic when it comes to removing heavy deposits.

I own a shop, and you do have a problem. I have used a drill bit to cut it our with by putting it in a pair of locking (vise grips) pliers, and turning it little by little. You don't want to drill a hole in something, or do damage. Using solvent to get it out with will cause damage to the O-2 sensor, and possibly the EGR valve, so you have to keep that gunk out of the rest of the engine. The best thing is to remove the intake, and drill, cut, or use cleaner/solvent to get it out with. If some of this is this plugged up, then you know there are other things plugged too, so this is why I say just remove the intake, and give it a good cleaning. If you use anything on the throttle body, then make sure its sensor safe. I have used throttle body cleaner, but I will use a long rag such as a shirt sleeve to stuff down inside the the throttle body to catch the gunk with. You don't want that crap down in the engine to where it can burn it, as this will damage the O-2 sensor for certain. I realize its a lot of work, but removing the intake is the only way to be sure you get it all out, and not damage other stuff. By the way; carburetor cleaner is for carburetors, and throttle body cleaner is for throttle bodies. There is a big difference.
Glad to help out, Good Luck!!!

The best way to solve this is to remove the complete TBI from the motor as it sounds as if the whole thing is plugged or the gasket has shifted. Take the TBI off but you don't have to disassemble it. I would pick at the carbon and use a spray cleaner to help to soften it up. Replace base gasket to intake and away you go.

Do not use carb cleaner it can "eat" the seals and o-rings go to your nearest mercury marine dealer and buy some Power Tune it dissipates carbon
