Hello everyone. First engine post I’ve made. Have a 13 Sonic 1.8L 173,000 kms on it, and as it’s slowly getting warmer here in the great white north I’ve noticed a couple things. #1 after it gets up to temp it idles down to like 650 rpm’s and the whole car vibrates, the mirror on the drivers side you can’t see out of like I have a big stereo system. #2 since this weird idle down shake like it’s misfiring I’ve noticed I have less brake assist. With the car off the pedal gets right hard. #3 no codes, check engine lights.. nothing… it’s got lots of power for such a little car… I come from a hemi powered 1500 so it’s good on fuel.. so I can’t compare. I’ve only owned the car a month and am slowly trying to learn more about it.
I’m thinking it’s a PCV issue and it’s causing the rough idle but not enough to set a code?? Or could it be a vacuum leak causing it and the brake issue or are the 2 un-related? The car was safetied and the brakes passed inspection but the tech said barely.
Any ideas?
