Hi Everyone, new to site, what a great resource!!!!

Recently bought a 280z '75 with fuel injection.Ran not so good. Cleaned all electrical connections, new dizzy cap, plugs, wires checked injectors, adjusted the AFM back to specs,checked fuel pump and lines,cheked TPS switch ,adjusted valves and went thru every diagnostic on the EFI bible. All Good! Problem? Slow torespond to throttle. Which led me taking throttle body out......It was clean on afm side of flap and sickly oily gunky on other..... what is that about? Any ideas?

Also what is the sensor on the exhaust manifold and where does it go? Mine just had a wire hanging from it....arghh.....
