Rough Idle and Electrical Problems.. HELP!

[Angelwankel]

Have you tried checking your AFM? TPS? CAS? Is it stock? A car that old people may have done all kinds of stuff to it, or there could be corrosion. I recomend the FSM and a bit of searching whether googling, or searching these forums or other rotary forums.

Maybe it sounds totally different, but it surges, idles rough, sounds like it randomly misses and cuts out... my car has a vacuum leak and it does what I call galloping whenever it's warmed up - but not the warm up cycle, I take it off of that - which I can imagine may be described as surging. It revs itself from anywhere between 600rpm-1100rpm, sometimes less as in 700-900rpm, while it does this, when it revs itself back down it sounds like its missing and cutting out, but that might my exhaust leak making that noise or maybe I can really hear it because of my exhaust leak. I don't know, I've never had an exhaust w/out a leak. Anyways, I was wondering if if is still stock, I took some emissions off of my car and we had to fiddle with the tps and the crank angle sensor just so my car will run, and that's without having my power steering hooked up, otherwise we may have had to have advanced the crank angle sensor a bit more.

it is stock, and i have cleaned the afm and it opens easy but havent been able to check it or the tps electrically, but what would cause the tach problem?

would fuel filter cause this? the inlet for fuel is pretty rusted who knows what inside looks like (previous owner didnt have a gas cap on it)

also i cleaned he intake and all piping cuz previous owner had everything coated with aiir filter oil.
