1988 944S Strange Idle variation

Engine

Vehicle Information: Model(924/944/968): 944S; Year: 1988; Body Type: Coupe; Total Mileage: 165000km (100 000 miles);

When cold, the engine will run fine at idle. If I raise to 2000 RPM for 5 sec or more and release the gas pedal, the rev will drop to 200-300 RPM and get back to 900 in about 2 secs. The car will also occasionnaly die on a red light or stop (due to the same rev change). Power loss also occurs during downshifting. The car "feels" like its being flodded by gas. The injectors has been removed and cleaned by a pro (ANSU), I replaced the idle valve and the cap, rotor, plugs are also new. I'm suspecting the TPS sensor or the O2 sensor. What is the best method to replace the TPS sensor on a 944S ?
