Car Shakes during IDLE - Toyota Yaris Forums

GeoffreyVB · 09-20-2019, 02:48 AM

I've noticed a similar issue with my Yaris. It's got what I would discribe as a shutter at idle it seems completely random, it's almost as if it just misses a cylinder sometimes. I got a OBD2 reader and was able to see that the vacuum does drop at the same time these little studders occur.
It's got about 160k miles on it, I'm thinking I'll try cleaning the MAF and I could change plugs? But it wasn't all that long ago I did that.

It's recently also started doing it other times than idle too. I tried. Checking the air fuel ratio with the OBD2 but it sounds like that might just give the target?
