I never got any recall letter , so Friday when i had my oil changed at the dealership i scheduled a recall for this past Monday. Had my wife drop off the 8 at 7am , by 12 noon the car was finished. I have a late model 05 RX-8 M/T.

Well my wife calls me up and says the car seems a bit peppier, i was like ok... maybe its all in her head.I asked what was on the description sheet, she said, they inspected the emissions,bakes, battery, starter, and the recall procedure, which all passed. She said no flash was mentioned on the sheet.(could have been included in the recall procedure)

So i told her i will drive it when i get home from work. Never got around to driving my 8 till the next day , which was yesterday. But on my way to work yesterday, i notice during idle on a cold start, the idel was ruff, like 500-650 ruff. Nornally its running 750-800 range. No biggy i figured its just cold....so after driving it and the 8 warmed up to its normal operating temp, every light i came to the idlel dipped down into the 550-600 range, almost seem like it wanted to cut off. So i just kept my foot on the gas lightley.

Now i get on it on the on ramp, and i notice my 8 starts pulling earlier than it does , for my 8 its around the high 4k -5k mark. Now it started pulling early around the early 4k mark and my midrange seems to have and i stress a "slightly" better pull to redline.-So don't go freaking out on me, its a slight improvement , not a night and day diffrence people.......

But the major diffrence i noticed was that under WOT and up shifting into the next gear, before the Recall , i would take it to 8500-redline then shift, then get a 1-2 second lag then my 8 would start to pull. I always called this rotor lag.....

Now after the recall under WOT and upshifting , i have no more rotor lag, i shift and the 8 keeps its momentum.


So the recall seem to fix and improve 2 issues but caused me to have a new one...Today the idle improved to 650, a little better , but still ruff. I am assuming maybe the computer is trying to relearn itself again. If the idle doesn't get better by friday i will have them adjust it.

I am happy that i didn't have to have my rotary replaced with a remanufactured one, that would of sucked!

Rotor Lag?, you know what though, I know a bunch of RX-7 guys and they all have that problem. they have to put it in neutral, pull up the e-brake and rev the engine. the "rotor lag" is most likely how you shift the car and at what rpm. I get that lag too whenever I don't shift right, but that I believe is you not the car.

I would love to believe that, but i shift pretty fast and before the recall it only happened when shifting at 8500-redline. Now it doesn't.....,had the car for 9 months now , so i am pretty confident on knowing how my car behaves. But thanks for the feedback.

My '05 seems similar. Since day one, it would always feel like it had no power for a second after a high-rev upshift, leading to really jerky operation. Since the recall work (reflash) it's much much better and has immediate power after the upshift. I have not noticed any difference in idle speed, but it does seem a lot less likely to stall in low speed operation, like backing out of a parking place.

Hopefully this is not just my imagination...

Nope ,its not because our symptoms were the same in the rotary lag department after a upshift under WOT. Now that we have the recall done, i don't have that lag anymore. So its no figment of our imagination. LOL!

Call & ask if they did the PCM a/k/a "reflash".
It should be MUCH improved, as in drastically & you should not have a problem that didn't exist before.
When you call, let us know what they say.

Should go away after a week or so. Most have reported this after reflash.
