Mazda RX8 has a hard time idling.
#27
Also I've unplugged the battery too had to replace the negative terminal but still the same
#29
That is a few days after I sprayed with brake clean, I have not yet replaced the gaskets I just ordered replacement gaskets the other day should be here probably by next week if not tomorrow. I do have a spare upper intake manifold that I threw on (I bought one because the seals on my EVAP purge valve not the solenoid got tore up and I couldn't find just those seals) and it actually seemed to bring the maf sensor rating up just a bit but I'm still idle hunting (the spare had used gaskets that weren't as smashing as mine) I'll check again after I get the new seals installed, I also noticed a whistle coming from the engine it sounds a lot like if you take the fuel jet air nozzle hose off the intake so maybe there's a vacuum leak elsewhere? I've also fully pulled my vacuum hoses and all of them are not cracked, torn, etc.

I did do a compression test and the results were not good...
2: I found my vacuum leak, I did a smoke test and my ssv was leaking turns out it was missing 1 screw that holds that metal plate (In the inside that sits on the shaft) against the ssv plate, I'll see if I can find a pic. fixed that car runs perfect!
now as for my compression
these results are from a rotary compression tester I bought, I should note that since my ssv wasn't working I couldn't actually redline my engine idk if that will affect compression or not.
results:
Front Rotor: 84, 82, 84 (PSI)
Rear Rotor: 81, 89, 90 (PSI)
This is the corrected reading at 250RPM (Upgraded starter)
I did get the upgraded starter before this, mainly because my old starter was starting to get weak even for cold starts and now both starts are basically instant.
I do not have compression symptoms yet but am already saving for a rebuild.
Please note that the tester I got does not support the barometer so It may be off since I live in missouri.
the exact area where I live I'm about 922 feet above sea level.

Sounds reasonable. It's a borderline engine, might go a while before it starts showing symptoms, or it could start tomorrow. You can probably stretch it out with premix, extra oil does provide some extra sealing. The good news is you don't have to rush to replace it, I guess?

Also it could be my coils too, I have oreily import directs. I have old oems but they were worn out. I don't remember if I said I had new oems but I thought these were OEM but they just said oe equivalent.
I guess my next step is OEM coils. U
I know it has new plugs and wires.
Anything else I could try, I've been using premix from Walmart the 2 cycle oil from the auto section, should I order the Mazda brand?
What's the name of it again?

Also have been using lucas FD rated Premix and so far it's running great!
one issue though, Awhile ago I lost an ac pipe (Well it got a hole in it) it was a certain pipe that I couldn't find used, so I had to order it via mazda it was back ordered, I got in the other day and went to put it on and I went to remove the overflow tank to make it easier to get to and the nipple that goes from the overflow tank to the radiator broke on the radiator so now I'm into a radiator
also I noticed my ac condenser had a hole in it too.
now for my question.
Should I go with a OEM stock radiator or just upgrade it?
and is there anything wrong with cheaping out on an ac condenser?
and yes I know how to vacuum down the system and charge it properly.
while i'm in the purchasing stage is there anything else I could put in to prolong it's life? I'm aware of the basic premixing, coils, plugs, etc but is there anything extra?
and with my engine not having much life left should I go for BHR coils or just keep getting stock ones?
also where would be a good source to buy the upgraded starter from? I see some on atkins rotary.

Yes I have an automatic 2004 rx8.

I don't think you have a ton of radiator upgrade options, being an automatic. The auto rad includes a trans cooling line which most of the usual upgrades don't.
I'm sure any OE replacement condenser will do. A/C has never been this car's strong point.
BHR vs OEM is more a question of how long you plan to keep the car... If it's for a long time, go BHR.

So probably will get BHR.
As for the condenser and radiator I just ordered the condenser from o'reilly's and got the radiator from a mazda dealer.
when I remove the trans cooler lines will the transmission fluid all drain out? I'm worried if I should clamp them before removing the lines.
