Motor Vibration Not Under Load - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Frishkorn · 10-17-2016, 03:29 PM

Been a while since I've been back to the group so first thing is first

Anyone else noticed they have vibration not under load between 1800 and 2000 RPM's?

Describe "vibration"?

If I hold the tach at 1800-2000 RPM's there is motor vibration almost akin to a cylinder misfiring. Under load I either can't feel it, or it doesn't happen. It's been doing this for a long time now, at least since a year after I owned the car. Was always quite subtle.

This weekend I noticed that when I back off the accelerator, it nearly stalled which it has never done. Checked the vibration at 2k and seems worse than it's ever been.

Hooked up my laptop with Ecutek, no codes were seen when I read them (figured maybe I didn't see the CEL at some point).

Will give it a try and see what I get. Can't say I ever noticed anything before though.

Pretty good!
Mine is a 14 with 97K on it so if any should vibrate...

Have tried it. Ya there is a bit at that range but nothing to worry about.
