well as you can see i just got my rx7 94 fd3s turbo...since i got it did the major tune ups and it runs fine now....i was just wondering...have you guys every had this problem when you first start your car up in the morning....it idles upon starting, then it dies out right after....u have to keep reving it for a bit to keep the car from dying out then as it warms up, it starts to hold idle...??? what is that due to..??

and another thing....is these RX7 known for flooding gas? i think that's what i did and it flooded my engine cuz the check engine like go on and it kills the car...when i try starting the car up again after driving the car hard....black smoke comes out the exhaust...it takes a while and couple cranks to start right up again...is there a way to prevent that?

there is so much stuff i'm learning about these rotary engines...but i really like these cars...lol...i'm just curious if others go through these problems too...other than that...awesome car man...!! i don't think i'll ever go back to my honda's again...lol...

 

yeah i didnt drive my car for about 6 hours and i started it up after it rained all day, the weather temp was about 55-60. i started my car and about 3 seconds later it died out. i started it back and it didnt die out. i didnt rev it or anything though.

 

Where are you at in Hawaii? If you are on the Big Island, you should PM me and we can talk. If on the other islands still PM me and talk on AIM.

It sounds as if you have a few different things going on at once. I would definetly not get on it hard or mess around to much until you at least pull the code off the ECU to see what the issue is with that.

PM me and we can go over that procedure or better yet search away and you will educate yourself
You want to be carefull other wise you teach yourself the hard way by blowing engines. and that gives the 7 a bad name when the owners don't take the time to learn.

welcome aboard and Aloha!

 

your best bet is to PM BigIslandSevens
He knows his stuff.

 

I wanna go to Hawaii

 

First off talk to "BigIslandSevens".

What I do to prevent flooding, it before I turn off my ignition, I rev it to approx 4000rpms then turn off the key. Havent had a flood for 2 years now...... Also I change my spark plugs less now too, but I would say you need to look at some small items on this FD you gotmaybe general tune-up parts(IE sparks plugs, wires), but this refers you back to the top of my post.

 

Just don't shut your car off until it is fully warmed up, thats what causes flooding.

 

 

if you switch your parking lights on that will hold your idle steady as well, but i have no idea if your engine bogs down enough to kill that added help as well

 

Isn't that only if you have leaky injectors?

 

BS? What the hell are you talking about? Most flooding cases are caused by cold shut down. Especially in the case of new owners who are not aware of the problem.

 

i've bought this car stock and with a rough idle...now i've tuned it up, it runs fine...changed the vaccum hoses, the plugs, the fuel filter...i've been driving it nicely for a while and it hasn't done it to me lately so i mean...i guess it's all on the driving of the car...when those things happened to me i drove the car to the extreme flooring it and i guess it musta flooded and caused the ECU to kill the car...dang...this is a nice car but it's just like a high maintenance chick...needs all the attention...lol...thanks for all your advice

 

i think that pertains to FC's mostly..whenever i shut off my fd after like 10, 15, 20 seconds of it being on, it starts up the next time around all the time..

 

Same here. I've done this plenty of times with my FD and it always starts right up. You can't always wait 5-10 minutes for the car to warm up when you have to move it a few feet.

 

FD's should have a problem with flooding when not warmed up before shutdown. Mazda has had this problem with all of it's rotary cars. Just check out the RX8club forum and do a search on "flooding". The RX8 is having the problem so it can't be compression or leaking injectors - some of the affected cars only have 5000 miles on them. About the only difference is they have Mazda Roadside Assistance to tow them in and a warranty that replaces their sparkplugs.

 

Thanks for your opinion cmanasseri. Have you personally seen an FD3S have startup problems that were related to flooding? From my experience, if the car is in good tune it will start and hold a steady idle just fine. If the car won't idle well, it's likely due to some other issue like a vacuum leak or ignition problems.

I've owned my '94 for a year now, and I've never experienced startup issues. I'm seeing about 15-20 inches of vacuum at idle, which should be an indicator of a healthy engine from what I've heard. I can't speak for the RX-8, because I don't own one. I've got a friend with one; I'll have to ask him about it.

According to your profile, cmanasseri, you own an '88, not a 3rd Gen. Why exactly did you feel the need to add your comment here?

I had to tune for cold weather and cold starts when I installed my haltech, and I had to turn the car off A LOT before it ever warm half way up.

had to get priming fuel right, post start fuel right, fuel coolant temp correction right, and idle speed controller cold settings...never flooded the engine and I'm definitely no genius.

 

Scotty305,
Sorry if I posted in the 3rd Gen Section, but I was doing a search on "flooding" and saw this thread. If you read my post again, you will see the only item I addressed was shutting the engine down before it has a chance to warm up can cause it to flood. I know there are other factors involved that can cause flooding but that's why I made the reference to the RX-8 flooding issue. These cars are all stock for the most part and have good compression so why are they flooding? The common theme with all the threads on the RX8club forum seems to be a cold shutdown of the engine. Mazda seems to be working on it but they are having a hard time deciding what to do. I was thinking about replacing my SUV with the RX-8 but can't really trust my wife to follow all the "rules" when driving a car with a rotary engine.

Once again, I apologize for my post, didn't try to act like I knew anything, just wanted to address one small item.

My car's been having flooding problem also. I don't think it is related to letting the engine warm up before shutting down the engine that much. My car would start fine until I leave it parked for overnight (6+ hours parked). Then I have to push start the car, and when the car finally starts it would rev to about 500-800 rpm and die immediately. Then I reset the ecu, and the car starts normally (needle jumps to 3k). I am thinking it's either the leaky injector or not strong enough spark.

 

I had the same problem once and it turned out to be a loose vacuum hose.

As far as the flooding goes, I've never had a problem in my 3 years of ownership with flooding and I occasionally have to start and shutoff my car before it is completely warmed up. I would check your spark plugs and see what kind of condition they're in.

 

Comon !!, nobody's gonna suggest checking the Map sensor ! ?

 

That's not what it looked like to me:



^^From my point of view, that is pure misinformation, without any sort of disclaimer or anything. The " 's " in FD's seems to indicate that your statement is true for more than one FD, possibly even all of them. Again, you seem to have no grounds for making such a strong statement. Then you went the extra mile by saying it's true for ALL the rotary cars made by Mazda. That kind of ignorance just won't fly, pal.


You're the one who made the misinformed comment. Don't get all butt-hurt because I asked you to back it up.
