I did a quick forum search and couldn't find my answer.
So, had my rx8 for 4 days now, she runs a dream, starts first pop, idles perfectly and has plenty of snot... BUT, my only issue is hot starts. From my house to the gas station, it takes about 30 mins, 90% is open rd driving. Once I finish filling, maybe 5 mins, it doesn't want to start. I hate to hold the key round and let it crank but it just doesn't fire up like it does from cold and its the only way I can get it to go. If I stop for like 45 mins, start up is fine.
Its a 2005 4spd auto and has 80,000kms, jap import.
I'm by no means technical and have no idea about codes and stuff, I've only ever had old school cars.
Just want to know possibly whats causing this, is it normal (water in the oil got me too) or is this the beginning of some bad news?

 

Could be bad news or it could be that it just needs some tlc .
Common issues :
bad battery
bad starter
bad coils
bad leads
bad plugs
or the big daddy ... bad compression

could be any one of those bad boys

 

4spd auto.
Check your compression and catalytic converter.
You should also try to understand what caused the problem to begin with. Bad ignition can kill the catalytic converter quick. Early pcm flashes had inadequate OMP rates etc.
It's a common problem, especially in early 4 speed auto models. A quick search will give you a lot to read.

 

Thanks, I was afraid you'd say that though sounds like money already
I just don't get how everything else seems great, when my skyline has issues, you know! the whole car runs like crap, but this is just one wee thing. Argh, frustration. I have alot to learn

 

If you live close to Hamilton I could diagnose it for you ...

 

Thanks Brettus but I'm down south, Oamaru. Pain in the **** cause I don't think we have a mazda dealership in town. I'd really only go to one of the reputable ones and they're in chch. Will have to read up, dig in, and see how much I can do on my own. Love rotas, but am begining to see why you don't see alot of them around.

 

They require you to be dedicated that is for sure .

Have a look at this thread for starters :

Thanks Brettus, feeling like a bit of a dick not finding that on my own
Second thread, awesome. Bummed out about the compression tester though, have a piston one, thought I could get away with that for free at least.
Given me alot to start with, will have to figure out if anything has been done by mazda to my girl before she got imported.
Thanks again for the help

 

You can
just take out the check valve and when you do the test watch the needle pulses . Better yet - take a video of the gauge while someone turns over the engine . Then review the video frame by frame .

 

Don't forget to count the revs in a given amount of time to determine the rpms.

 

 

Oh wicked, thats good, very good.
Hey just cause I've got you on the thread, being a fellow kiwi could you tell me what the availability of 6 spd gear boxes are in nz. I can't find any and im pretty keen to upscale. I thought the 4spd would be fine but this car just makes me want MORE
Oh and is there an easy way on the net to find out if my car has had any recall or warranty jobs, or do I just have to call mazda?
Thanks again

 

Not sure if anyone here has done that conversion (full motor and g/box has been done) but I think it would be a major. You would be better to sell the car and move to a 6 speed model.

I think you would like my turbo



Think you would , yes .

 

But I just got it lol I love the car itself. Beaut colour, simple kit, wiked interior. Hmmm turbo... I do like that idea, but I think I like the whine of a supercharger.
Perhaps I should research some options, then by the time my finance is paid off, I should have a clearer idea in mind.
Spoke to some dick this morning who basically called me an idiot (which may or may not be true) for buying my car! I was put onto him as he rebuilds rotarys, and I wanted to ask him some questions regarding the compression test. He asked for some history on the car, which is in the 1st post, and no, I didn't get it checked out before I brought it whatever. So he procceded to rant about it being a time bomb and blah blah blah, shoulda blah blah blah. And heres me just thinking WTF mate I just wanted some advice, not a goddam earfull.
So now I'm feeling like a scalded f*#king cat. Yes it was an impulse buy and yes I'm a relatively clueless female but I'm giving it a crack. I really didn't need that ****
Sorry, hadta blat

 

Oh boy - that is not what you want to hear about your pride and joy . Your description of events did give me a chuckle though .
Think of it this way - you have a unique car that is a blast to drive and looks fantastic. By owning one you set yourself apart from all the ho-hum toyota driving , jersey wearing boring farts out there.
But that comes at a price .

If compression is your issue all is not lost - do a decarb .

 

he was right, the point being the sooner you accept and learn from your mistakes whether you want to hear about them or not the better off you will be the next time around ... but you'll probably just listen to what you want to hear and go do a pointless decarb that won't change anything

 

I have seen a 0psi (on one rotor) engine resurrected to run perfectly doing one of those "pointless decarbs" .

using the same technique as this guy

 

Hey unless you can't read, you'll see that I went for advice for a problem I KNOW I HAVE, I'm not in any kind of denial, I just don't think it was neccesary for him to be an *******. Either he has a problem with 'females' or like you, he thinks he knows everything.
If you don't have anything constructive to add to this post, then **** off. I'm here to LEARN and sort out my car, not to listen to **** from egotistic *******!

 

Yeah, I'm just a tad defensive I've been told that many times that females shouldn't be allowed near cars that the minute someone pairs 'idiot' and 'female', it's on! I bought the car knowing that at some stage it'd blow an engine, I just hoped, not so soonish.

Oh thats wicked news.
The hot start was better when I took her out last night. Maybe it's just been due a good thrash? Going to check out my coils, plugs, leads etc on Monday so I've got my fingers crossed it's something simple. My warranty forms are on their way so I can see what I'm covered for incase it is compression. If my cover won't front up with 70% + then I'll give that decarb a crack I think.
Although it'd be primo to start off with a fresh engine, then I know it'll be looked after.

 

Don't listen to Team - he is a grumpy old man that rarely has anything good to say .

To add to the above , i'm sure my compression is not good and i had hot starting issues as well . Fitting the faster upgraded starter motor completely cured the issue for me . another Kiwi on here had exactly the same experience.
Fast starter speed and good ignition will mask weak compression .

 

Perhaps I should just replace the lot? I got my insurance forms today from autosure, (not sure if you know them or not) all looks pretty legit. They wont cover stuff like the plugs and coils, or clutches and brake pads which seems pretty fair I guess, but they'll pay for any major mechanical breakdown to the market value of the car, obviously that wasn't caused by neglect or faulty parts.
Feeling much better now
Wheres the best place to get genuine mazda parts? .... cheaply
Can't wait to get stuck in and have her running perfect.
Brettus, you have saved my sanity this week thanks

 

hey,,

you for got to ask her what she was wearing!!!!

and i am impressed that the faster starter did it. i am with a old 120k motor and still the old style starter gets it done..

i am blessed!

beers

 

Mine did too - for a long time . but shove 12psi of boost up it for 30000 miles and then see how you get on .

 

I'm a farmer, so basically overalls, gumboots and plenty of cowshit
try sex that up.... fool

 

Done:
