Rx7 idle problem
Sup guys just got an Rx7 not too long ago. I already know theres a ton of problems with it but its driveable and it feels pretty good as it is.
So I have been reading A LOT on this forum about all my problems but I need more definite conclusions. Here are some parameters about my situation:
I have a '92 Rx7 FD seq. turbo. Guy I bought it off said the engine was rebuilt and has 9k km driven on it. I think he said it was a series 8. Also said he removed the rats nest.
1. I know my TPS isn't working properly because I followed the instructions on the FAQ to test it and only one wire gives me reading and its stuck on 4.6v.
2. I idle at around 900-1100 ( it jumps up and down ) and i get 10-11inhg vacuum. ( this part really worries me, ive read that means im losing compression in the engine which = rebuild? ) Car also shakes
3. While driving I can only reach 6-7 psi of boost on the primary turbo. second turbo never kicks in most likely because I can't reach 8psi on the primary.
4. There's a bit of oil in the UIM, not sure if thats cause its been sitting in my garage for a while ( haven't driven it in a month )
Guy I bought it off gave me a fuel filter he bought and was going to change the current one with but never did it. Not sure if that means the fuel filter isn't working and I don't know if it ties into any of my problems.
Here's a video of the idling while cold ( had just started it maybe 20 seconds before the video ):

If there's any other info I can supply to more accurately conclude all the problems please let me know.

K so I fixed the TPS , it wasn't put on properly by the previous owner. My idle is now at ~800 which is good but it still jumps a tiny bit.
I drove the car around today and I was getting black smoke. Can't be good right
Vacuum reading at idle is still at about 10-12 inhg
I can get to 6 psi of boost before the fuel cuts so I'm assuming I may have caused a bigger leak when I was working around the engine?
Would be nice to get some help here. Does no one post in the new member technical section? =\
