Gas Pedal Delay

so something is dumping too much heat in the im causing this bogging.i cant get on the car too long without stopping before i experience this bogging.there has to be one thing that is dumping too much heat into the im besides the obvious heat soak. pcv hoses are not helping for sure.i plan to remedy some of that heat with oil catch cans.i will be looking to see what else i can do to eliminate as much heat as possible.

has anyone done a egr delete or is it even possible on this engine ? that would eliminate more heat from going into the im.and does anyone have a link showing the schematics and what is what on this engine ? i would surely appreciate it !

on a side note,when i have had the bogging,i stopped,popped the hood, and immediately put my hands on the tb's and they were cool to the touch in 82 degree ambient temp.so i know the intake and tb's are not the blame.pcv hoses on the other hand were hot.what is that thing on the back of the engine towards the top that looks like a small motor ? that thing gets very hot.sorry for some of these questions.i have done alot of research on here already and these few things is all i need the answers too por favor.

edit;and my oil temps were 195-205

Is it possible that the PCV valves are getting stuck open when the engine gets hot? That will cause a leaning effect, probably more pronounced at low RPM's.

possible.i will be trouble shooting everything i can think of to resolve this issue.i will find the culprit eventually.

EDIT; come to think about it,those pcv hoses ARE dumping extra heat into the front two piston holes.i will do something about this, this weekend and see what my results are for that.

Are the PCVs active? Or are they a standard passive valve on this car?
(I sold my Z, so I don't really have a way to check anymore)
