fearing the worst
As I was exitinga parking lot two days after buying my first FD, I started to accelerate and as I went to push the clutch in to shift into second, it didnt feel "right." The car was running like complete ****, and my throwout bearing was making wayy more noise then it usually does.
So I get it to the side of the road, shut it down, look over everything, and try to start it again, no go, it wont turn over. I get someone to bring me some gas, thinking it may have ran out (gas gauge apparently not working :/) and try it again, after some effort it turned over, but was still running like ***, Idleing around 800rpm and just sounding terrible.
This came at a very large surprise to me, as it made the six hour drive home just fine, with the exception of a blown intercooler hose, which I repaired when I arrived home.
I'm going to load it on my fathers trailer today and get it gome to run a compression test on it, but I'm fearing the worst for my 3 day old car.

I blew an engine due to an apex seal and it's true it they run like *** when they let go but there is no way that it would idle. I had to keep the thing almost floored to keep it running and even then it was up around 4-5K.
Is there any smoke coming out of the exhaust?

Start with the easy stuff first - MAP sensor hose popped off?
When in doubt, do a compression test, that will tell you for certain.

Ive had customers daily drive a blown apex seal fd for a month at a time Believe me, Ive seen a lot idle and run but not correctly. They will usually have black fuel smoke coming out the exhaust and you can watch the needle bounce on the boost gauge at idle.
My experience is with only one so this sucks, I was hoping it would be something else for this guy. maybe if he's not blowing too much smoke it still could be something else.

I'll run over in a bit and check her out, if I recall it wasn't smoking very bad, if at all. The boost gauge was reading anywhere from -15 to -5 at "idle" if you can even call it that.

+1 to Check the MAP sensor...
Every FD owner should pull the Vacuum line off the MAP sensor to experience what this is like. After reading so many, my FD runs terrible now, threads I went ahead and pulled the line to make it super loose from the MAP in the name of science (or rather me learning something new - Hey this might make a great short YouTube video!!).
Check this out, as its right next to the elbow and if you did any oil filter checks chances are it popped off.

little update here, checked the MAP sensor, its all good, and all the hoses are connected to it. I'm going over in about two hours with a trailer to load it up and bring it home. On the upside it started right up, however, it still ran like ****.

Haven't checked compression yet, but i'd venture to say its blown. And to make things even better, the transmission ate it somewhere in the midst of the whole incident yesterday. Although I knew it was coming (throwout bearing VERY noisy, 3rd, 4th, AND 5th gear grinds) its awfully convenient that they both went at the same time. I was able to drive her up on the trailer, had to start it in gear though, and boy oh boy was she reluctant to drive up those ramps.

update: just ran a poor mans compression test, with the result being psst.............psst...........psst.............p sst. I'm no mechanic, but I do have a friend who is coming to look at it sometime this week and give me a full diagnosis. what are the chances that the rotor and housing are still intact, and I'll only need new seals?
Also, I bought this car off the forums (https://www.rx7club.com/3rd-generation-rx-7-1993-2002-vehicles-107/1994-mazda-rx-7-pep-858672/) and the engine supposedly only had 25k on it.
