well, dont mess with mixture, and unless all your emissions are off, it shouldnt smell bad (or bad enough to say something like that).

 

well lets just say i just bought the car and the guy has a str8 pipe out like a go cart with no exhaust and sounds like MAJOR RICE! but i dont know if that does anything.... i live in FL and we dont have emissions here and if we do i dont think they really care i dont have a Cat or exhaust and the car is pretty loud when accelerated and it does smell realy bad i really dont know what it is......

 

its running rich. if you pot a high flow cat on it then the smell will go away, but its only because the cat is masking the problem. i dont know how to set mixture, i thought that was the computers job.

 

kk thnx ill see if i get one from rx7store.net or something

No no no try to find the problem before covering it up with a cat (and if u put a cat on an overly rich car then the cat will be all fucked up in a couple years so its not worth it). Is there any mods other then the exhaust? Also, is your car a turbo? If not then having no backpressure is bad as far as I know. Also your aux ports are closed unless they were wired open (if non-turbo). Is there bigger injectors or new fuel pump or some ****? I really can't think of anything that would cause a mostly stock car to run that rich.
No emmisions in florida, lucky ***'s . It doesn't matter what you have (cats etc).

 

Dude! Any FC with removed emissions is going to REEK! Thats part of the fuN!

 

at least its not leaning then-BOOM!

 

Check the BAC Valve. It's responsible for idle under load, i.e., A/C.

 

ok only upgrades is exhaust its exhaust and s str8 pipe thats it its an 88 GXL N/A ummm if the guy i bought it from didnt do this wired up aux ports thing how can i fix this cause lets say im working on the car while engine is running to see how its going in a second my shop smells like *** all over the place =(

I doubt the aux port thing has anything to do with the smell - it does give a performance loss (like 20HP Ive read) though. If J-Rat is correct, and having a straight pipe makes it smell, then I guess buy a cat and muffler. It sounds like you need to check the BAC valve like runningdeer said. What does it idle at (RPMs) with no load (like in neutral with no AC)? Does it hold a steady idle? What RPM does it drop to when you turn the AC on? BTW I don't think that the AC issue and the smelling bad are related. I would check the BAC valve, and get a hi-flo cat and muffler and cut the straight pipe as needed lol. Good luck!

 

Can you purchase any high flow cat or do you have to buy a specific rotary one?

 

ok the car runs in neutral at like 900 to 1000 rpm with AC on and in gear will go down to like 700 rpm or a lil higher but the thing is it has a thing that ill accelerate it and jumps to like 4k and starts heading down itll go str8 to shutting off =/ but i dont know about this aux thing i guess id have to call the guy (the guy i bought it f rom) and check if he did the aux port thing but still i need to gain HP NOT LOSE IT!!! lol thats the only reason im intrested in finding out about this... would greatly appreciate help i really need to gain some HP on my car 13b N/A Motor with 130k miles on it if motor blows will get new one and put aftermarket parts from old one to new one.....

** siameseNA- any cat will work, but get a catco high flow cat. those are the best, and dont have much of a performance loss.

 

Do a full tuneup. This should be the first thing every new FC owner should do...Grab a Haynes or other repair manual and follow the steps.

 

Not true, most cats aren't made for rotaries, you need specific ones for them or they will be fucked up really quickly and be a waste of money.

 

I would actually go with a Bonez cat, tons of people on here run them so they must be good for rotaries. Do a full tuneup (http://www.1300cc.com/howto/how2/general.htm) and report back. BTW about the idle thing, it really sounds like BAC valve...Check out this how-to on BAC Valve cleaning (doesn't look too hard, but I would do tune-up before BAC valve cleaning to see if it goes away): http://www.1300cc.com/howto/how2/bac.htm

BTW check out the howtos here: http://www.1300cc.com/how2.html they are awesome! Good luck!
