1991 Acura Integra - idle problem??

hey guys. I just got this integra. I think it has an idleing problem? the previous owner said the following.... " it has 153,000 miles. I think it has a problem with the TPS (throttle positioning sensor) and also has an oil leak. The car runs great other than it idles to high at about 2000 rpms. As well as got the IACV replaced. The TPS I swapped out of an old head laying around. The idle air control valve is what was replaced and still didn't adjust the idle..." The distruibutor cap looks normal, no cracks or serious wear. I recorded a video and put it on youtube for a better diagnosis from anyone that would like to contribute and help me out. Take a look. Any ideas? Thanks!!!

96 Integra LS Idle Problem (FIXED)
I say it's not an rough idle in the beginning but it is only in park and neutral. The other gears are just steady high idles. IACV replaced, all coolant hoses changed, and coolant flush done. FIX: It was simply some low idle screw that were extremely off. It's in the area under the IACV and two screws are covering it in gold dome shape. 96 Integras don't have FITVs. They stopped putting them in 95
