Has anyone's RX-8 AT slowed down, stalled, then started back up in a few minutes, run very slow, then returned back to normal? This happened to me (probably because of the heat). The dealer got a few cases like this and all were AT's. They have not been able to pinpoint the problem.

 

wow...i wasn't aware that you could stall the AT

 

This happened to me (probably because of the heat).

No problems here either. How hot are you talking ? Any other driving conditions you were aware of ?

never happened to me yet... maybe the ECU runs on Windows???

 

Normal driving, but in vegas summer heat- maybe 105 to 110 degrees.

 

No problems here.

 

happened to me once about six months ago

but it never happened since

 

I have this happen every once in a while. Almost got t-boned because she stalled in the middle of an intersection. Only happens when my 8 is cold, usually in the morning.

 

When its cold? So your problem doesnt have anything to do with the heat? The only other person i know with an 8 had the problem in the heat too, like me.

 

mine was not on a cold start

 

Were you in AT mode or shift mode?

Mine will start to stall if I down shift to 1st and it starts to pull high revs, if I don't have on the gas. Kind of like down shifting a manual. It hits the high rev, drops to about 200 rpm, then returns to normal.

I don't know if it's just the weather

 

Mine has only happened when my 8 is cold (first drive in the morning) and I press the gas pedal "hard." I'm not stomping on it but I'm pressing it to get the car moving from a complete stop (Stop Sign).

 

Were you in AT mode or shift mode?

It had nothing to do with manual shift mode. The engine quickly but gradually lost power and stopped during normal driving.

 

Both, believe it or not. AT mode and shift mode.

With this "issue" and my crappy gas mileage, I'm starting to think there is something programmed incorrectly with my ECU...

 

Scary thought. If Mazda were to follow the M$FT support model, they would discontinue support on all their crappy ECU code and force us to upgrade to the new and improved "ECU 2005" code for $199 :D Which, BTW, would run very slowly on the old ECU...

 

it did it again. twice. i'm taking it to the dealer tomorrow.

 

Keep us posted.

 

Well, last couple of days I almost stalled two times, both times I had just started my car, driving in normal mode. The car kinda lurched a little and the check engine light came on, but it was ok once it was warmed up... I don't know, I'm taking my in for a checkup this Friday.

 

i got my car back. They told me a few japanese mazda guys came over to check the problem out. It seems the problem is only with a few cars that were sold at my dealer, and nowhere else in the U.S. My friend's 8 got taken to death valley for testing. We are waiting for more info.

 

Huh? They took HIS car to Death Valley for testing?!

 

yep

 

Does your idle hold still or does is run rough (fluctuate). If it fluates, you probly have a vacuum leak somewhere. Maybe a gasket is leaking or a hole in vacuum hose.

Otherwise, maybe it's a transmission ECU issue.

 

According to the dealer, there's nothing wrong with my car, they couldn't find any error codes, they suspect it might be a bad batch of gasoline causing the car to misfire....I don't know...

 

Hi! I have had the same problem.
IT happens at the same place.... and it's not when it's hot.

I start my 8, and drive down the hill.
I come to the stop sign and stop for 3 seconds.
When I begin to accelerate, the car looses power. If i continue to accelerate and not take my foot off of the accelerator the car will turn off while I am trying to cross the intersection.

I have come to my personal conclusion that:
This problem is due to the temperature of the engine. If the engine is still cold.. it will do this. Ive done the same thing when the engine is warm... and it doesnt stall.

You may want to check about the "Power Start Recall" That also helped stop the problem.

 

Guess what? Two days after the dealer checked my car, the check engine light came back on again.
This time, the tech is talking with someone in Mazda, preliminary diagnostic say leaked coolant in the engine, they'll have a better idea by Monday...
