So I have searched and nothing.

The car has been in storage for about 5 months now. I took all steps to unstore the vehicle and cranked her over.

Of course it had a hard time starting but it finally caught with some fancy pedal work and I let it sit at about 3000-3500. I slowly let it idle down but it keeps dying once it gets to about 1000.

Any suggestions?

right sorry!

1988 RX7 N/A Coupe

It has a cone filter...thats it

As for steps taken, I followed aaroncake'sa steps to unstoring vehicle. Mine was improperly stored so I followed those steps for the most part as it was only stored for 5 months.

Drain flush and refill coolant. Replaced BACV.
Charged battery.
Oil and filter change.
Poured oil into leading spark plug holes. (A very small amount)
Fresh fuel with some injector cleaner. (Fuel filter will be changed after a couple hundred km's as well as tranny and diff. fluids.)
I have new spark plugs but did not install them because i did not want them getting fouled by first start up.

When I was first starting it, it was smoking like crazy. I mean cheech and chong smokey. Cranked weak at the beginning due to lack of compression obviously but had a very strong crank afterwards. It catches and sounds very strong when I hold the gas at a certain rpm but dies when it tries to idle.

The car ran perfectly last year with the exception a bad idle on startup due to BACV. It did have a very hard time starting in the colder months of last year. This is my baby and love it to death, please help me keep it started guys!!!

Sounds like some varnishing of fuel in the fuel system. It should sort itself out after a while of running. does it still start? Keep the battery topped off while your messing with it. change out the plugs once you get it started. Be patient. if the injectors are clogged you will have issues with most aspects of running especially idle. I would suspect a vacuum leak is the cause of your previous bad idle rather than your BAC. The BAC functions more while the AC is engaged or when your foot is on the brake and drawing vacuum, not directly idle related. Check linkaged for free movement and no binding or sticking. also your coolant levels have a big effect on the throttle body functions on a stock vehicle. You might try replacing the thermostat with a MAZDA unit. Don't use a cheap aftermarket one 'cause they won't work right.

I should have went into further detail about the idle problem last year. It was a bouncing idle as opposed to an erratic idle. I tested the BACV for resistance and it was off. As well i unplugged it while the engine was running and no idle change. That was definetly the problem with the bouncing idle. I checked for Vacuum leaks and timing and all that great stuff. I narowed it down to the BAC.

Back to the start up part. It starts and catches a couple times and dies immediately but then sometimes it will catch and stay started but once it winds down it stalls. i was thinking about taking the injectors out and cleaning them. Maybe i should.

I was also thinking about getting it started, keep it revved up and take it for a spin down the street to put a load on it and different a/f perameters and maybe that will clear in the injector problem.

Its on axle stands right now, as i am waiting for my new tires.

So the bouncing idle stopped when the BAC was unplugged? You weren't very clear on that point. You say it didn't change when you unplugged it? so what makes you think that's the trouble? I would suspect a vacuum leak somewhere... what about the intake feed to the BAC? did you hook that back up? again I would say a vacuum leak is the culprit... get a propane tank with nozzle and turn it slightly on but not ignited..... hold it around different parts of the intake while the car is running... if the rpm's increase you have found a vacuum leak... Don't smoke a cigarette while doing this!! or a Doobey either!!!

The idle problem was it had a bouncing idle while warming up and then would go away. Once it was running properly ( not bouncing) I unplugged the BAC and nothing happened the idle stayed the same. As well the resistance was off from spec. I havnt has time to start it yet since this so im going to go test her out right now.

I have checked for leaks already with some carb cleaner and was all good. Im going to mess around with it some more and report.

Propane+ doobey or cig= explosion......got it, thanks!hahaha

Don't rule out a vacuum leak. I've checked everything(I think) on mine at least 4 times and I still can't find my vacuum leak.

i'm not a big engine guy, i would like to be but i just don't have the time to learn so i'm sorry if this turns out to be a pointless post.

i do have a similiar problem. i bought the car with it, 1986; stock except performance mufflers; non turbo. my idle bounces. i had it checked out at an import auto place and they told me the fuel injectors need to be replaced but i put it off until this year because of money reasons and it was going to be stored over the winter. this year i took it back to the same place and them being kind of dumb only put in a new fuel regulator which seemed to fix the problem but it didn't all the way. occasionally when i'm dropping in speed from 60 or higher to stop it will just stall on the way down. and when shifting out of reverse and into first my rpm's will drop really low and the car will shudder and then rev to 1500 and then drop again to about 700 and idle. also when i start my rpms rev which i know is normal in any car but it then drops from about 2500 to 1000 then back up to 1300 and then back to 700 where it sits. i know i have a small exhaust leak but i don't think that is affecting it at all.

i have tried running injector cleaner in it twice and it seems to lessen the problem temporarily but having an import shop not fix injectors confuses me when that seems to be the problem.

sorry again if this doesn't help at all, just thought maybe i had a few things not already typed out. let me know if you ever get it fixed and what it ended up being.

OK guys she is purring like a tiger ready to pounce!!!!hahaha

It turns out when I took of the intake pipe from the filter to the trottle body I forgot to plug the feed for the BAC back in. It started without problems and idles like a champ!

Thanks to everybody for the input. Especially ramses666 as he pointed out that I could have forget to plug it back into the BAC. Thanks dude!

jstieber try purging the injectors and changing the fuel filter. You definetly have a fuel problem. And avoid going to just any import shop, they will try to play you like they know about rotaries and dry you out of cash. Find a rotary specialist!

Thanks everybody!!!

i'm glad you got your car running again. i took mine to a shop i trusted but i'm not so sure about that anymore. its in there again and i'm hoping they are fixing the problem for me again without cost because they screwed up the first time. they apparently have a "mazda specialist". i live in northern michigan and my options for rotary mechanics is limited.
