Have a 2015 Equinox LTZ. Very nice well kept overall but has a flashing service light along with Service Stabiltrak message. Idles & runs rough. 150,000 miles. Has been nickel & diming for past year. Going tomorrow to look at 2019 equinox. Sell the 2015 as is, trade in as is or fix then Sell.
Local shop plugged it in and getting misfire on cylinder 5.

I'd fix it. It'* probably just a bad coil. Has it ever had spark plugs replaced? If not then that'* definitely needed. If you're going to trade it in, they'll probably only give you a few hundred bucks for it with a flashing check engine light.

Plugs changed 6 months ago. Number 2 coil changed out. Now needing to know where is #5 cylinder located? Diagrams are confusing on Google searches. Pics show it'* located on front drivers side but another explanation says it'* on backside. of course engine sits sideways.

This is the 2013 but for what you need it'* perfect.

Here you go:

Got it. Number 5 easy to change out. No intake to remove. Running smooth again & no light. Thanks

Cool!

Thanks for letting us know how it turned out!
