When running the 8 today, something unusual happened. I was running car to about 8k-8500rpms, and suddenly car bogged down like a rev limiter kicking in and check engine light blinked. I hadn't reached 8krpms yet either. Since I have been running 87 octane lately, I was wondering if that was a knock sensor of some kind, and the reason this happened was due to low octane. The engine light just blinked a few times, then stopped. It doesn't do it all the time, just occasionally. Has anyone else experienced this? I am pretty sure high octane fuel will stop this form happening, but I am still a bit concerned. Thanks!!

 

I've seen this before on the forum, it's related to misfire. Do a search for it. It could also be the knock sensor, the RX-8 has a very good one that retards timing and significantly reduces power when it detects any knock to save the engine from damage.

 

bet you were at less than a .25 tank of gas. had some fuel stavation and threw a cal.

been there got that.

Yeah.. was your gas low? This happened to me when I was hammering my car down the turnpike. It'll be a misfire code.
