Idle Air Control Valve
 

Hi all. My RX8 has been giving me problems, but I thought it was due to low compression. The thing is, I still have some get up and go and all that good stuff. When I come to a stop or just resting at idle, the car often dies and takes hours to finally get it to start back up. Last night I got my code read and the guy told me that one of the codes was saying something about a problem with my IACV and he was able to tell me word for word all of the things that my car would do and when it would do it before I told him anything. I can't find where to buy one, but should I try cleaning the one that is on there now? I've been searching for a DIY, but I couldn't find it. I'm wanting to try to clean the MAF sensor, Throttle Body and the IACV today when I get home. Any suggestions guys? I wrecked my daily driver last week and this RX8 is all I'm left with.

The 8 doesn't have an IACV ... it performs its IAC functions through the manipulation of the throttle body. Are you sure you dont have a vacuum leak.

Also, 5 common causes of bad idle / stalling

1. poor compression
2. dirty maf causing poor readings
3. dirty ess sensor causing poor readings
4. large vacuum leak
5. ignition failure

1. I know for a fact the compression is low. I just don't remember how low.
2. Will clean today. I think I saw a DIY
3. Will try to clean today. I think I saw a DIY on that

Is the throttle body something I can try to clean?

You could, but i doubt that to be the source of your problems.

When was the last time you changed plugs and coils

Never changed either. We bought the car already having problems. I'm just trying make it a week or two. I'm going to do an LS1 swap.

Edit: I've been convinced to doing a LS1 swap. I'm not doing ANYTHING but buying the stuff. I don't know what I'm getting into. I don't know the pro/cons. I'm just hoping to have a reliable vehicle and not having to spend more than 2k for it.

Ls1 swap for less than 2k?

Good luck with that, not to mention all kinds of weird problem u get after the swap

Uh oh. What do you mean? I'm gonna buy the motor and computer and wires for 800, MSD for 300, drive shaft for 300 and I dunno how much for installation. What problems am I gonna have bud?

What kinda computer are you gonna run? You'll most likely lose all stock electronics like ABS, traction control, cruise control and your speedometer prob won't work. Plus you'll have to figure out how to fit it in (mounts, wiring, etc). Good luck.

Oh damn I'm not sure of any of that. The guy told me he can get me an LS1 with computer and all the wires for about 800-1000. He told me I'd have to buy a MSD and a drive shaft. I guess I can do without all that other stuff because I can't really drive the car without it cutting off and not cranking back up when i come to a stop.

No offense to you man, but u gotta get a freaking clue before u start any weird shit like that.

We seen enough morons here who said the exact same crap as you, high goals, but without of any knowledge. Ur buddy can get those crap, but does ur buddy knows how to it? Cuz it looks like neither u nor ur buddy has a clue. And most jackasses who talk shit to me, most just end up with a non running and totally hacked up car and sold on eBay with bs like oh I don't have the time to finish. Or simply disappeared cuz they were too ashame of themselves, oh of course, did I mention they lost money + a non working car?

Think twice buddy

If the engine is bad, why not just get a reman from mazda? There only like 2-3k and bolt right in... No custom work needed.

No offense taken. Like i said before I'm not actually doing any of the work. The guy that's going to do everything did it to his car a year or two ago. From what I've been reading on the site though it seems like that's the way people are going now with little to no problems. He told me more people are moving on to LS3s but I dunno what that means.

As far as the cats who talk shit to you or whatever that's none of my concern. Thanks for the insight though. I'm sure as hell gonna ask what the pro/cons are. I'm just trying to get a dependable car. I'm not doing the motor swap for speed.

Honestly just the fear of having another engine with low compression. I was told a rebuilt one would be around 4-5k from the dealership. I don't want to spend that kind of money on an engine i don't fully understand nor that I can even begin to work on.

Sell the car, it's not for you.

Not at all. I told my gf not to buy the shit in the first place smh. Now I'm stuck trying to drive it. Thanks for all the help fellas.

That's what happens when you let women call the shots.

Maaaaaaan I just got a quote from a different guy here in Houston and he told me just 1500 for some kit and then another 1500 for a header system

Every time when I sit in a swap car, it always have some weird issue, but all their owners said what problem?

U can get a properly build engine from 2- 10 grand ish, it really depends on what you want, saves u a lot of potential headache from the swap. U can pm mazmart and rotaryresurrection for more info, Just a little 0.02

Good luck buddy

Are you sure, he said 2 and not $20,000. LSX swaps are fairly lengthy and pricey procedures and entails about %99 more then just, motor, ECU, driveshaft hey budda bing were driving!!!

It takes a huge investment in hours and custom fabrication skills including custom motor mounts, custom headers, custom cooling system, modifications to the steering rack setup, parts of the sub frame being cut and re-welded, the stock lsX oil pan doesn’t work, you need a custom oil pan and the oil pickup inside the pan has to be custom, the stock gearing in the rx8's rear end makes first gear useless LSX trannys are geared super low, the 8 uses CAN bus cluster making it useless after the swap. I could really go on, but this almost seems like a troll thread it's so ridiculous

who started this poopy thread, oh it was Mr. Exlax ... :cwm27:

man if u want I have a perfectly good 13b re for sale I live the same town all u have to do Is find someone to build u mounts and ur going to have to cut up the oil pan but other than that shit will work with new ecu and there's a shop in ft. worth that does the ls1 swaps for 5gs

If you cant rebuild yourself you shouldn't own a rotary. Just going to piss more money away every time you blow it up.

round 2 for poopiness ...
