Checked my plugs and they are all wet fouled.

Why would you assume that? Is it oil residue? Valve guide seals maybe 

Take a propane flame to it and see if it burns off .

way rich. OR wrong heat range. is it burning oil (blue smoke) or gas (black smoke).

1st thing is to get a compression test to gauge the overall health of the compression. is this a FI or carb?

If FI check all the sensors/fuel pressure/connections/grounds. Check for leaking cold start valve. fuel pressure is critical and must be controlled for FI to work.

If carb IDK.

You should add your car details to a sig, or at least tell people what you're working with in your posts. 

Pretty sure it's a 240Z, based on the stuck heat lever post.  Looks like the plug was firing for a while.  Need all of the details on the engine though, and the plug, to make a better guess.

Ok will do. I've been technically unsavy lately. Must be old age. 

that black and no smoke? hmmm that seem odd. and they all look like that?

choke function working correct? (wont start without it, pulling it when warm makes engine stubble rich).

how long were those plugs in use? do you drive it aggressively (open it up and rev up to 4-5  k between shifts or do you loaf around at low rpms a lot)?

Sorry don't know just got the car. Yes I intend to give her an Italian tuneup once register and with new plugs. I drive in between agressive and safe/normal.
