Problem with my '87 FC3S TII

Okay, so, this is my second TII. I'm not a rotary expert, at all. I've been reading up a lot, but I really have no clue what's going on now. I attempted to search for the answer myself but couldn't really find anything that was similar to my situation.

Okay, here we go.

Now, for one reason or another, it takes my FC a few seconds to start up, I figured there's a bad connection somewhere, but I'm not sure. It idles just fine, around 750rpms.

The problem is, when I give it gas, it starts to stall and shut off, even backfire sometimes. I really have no clue what's going on. If I slightly step on the accelerator, it'll rev up, but if I push it a little more, the car starts to stall. Is this something serious? Do I need to give more info? I'm not really sure what's going on at all.

Hmmm, after a lot of thinking, I was wondering could this possibly be a vac leak? I mean, it revs to I dunno, about 1.5k and then stops. As I release the gas, it revs again.

mine does the same thing. just let it warm up and see if it stops. the aws will raise the idle when you initially start the car.

All right thanks, that worked.

Now, is there a fix for this to stop it from happening completely?
