Service Stabilitrak 
Solved
Chevrolet Equinox 2015 LT 93300 miles
I had an emissions warranty on my car after code p0411. They replaced secondary air valve. They cleaned secondary air ports in cylinder head (said excessively clogged). Got my car, 10 min later, engine light is flashing and service stabilitrak came on. Took my car back, dealership said code p030 cylinder #1 misfire. I changed all spark plugs and coils at dad’s house. Drove it home fine. Next day, I went fast and got the same error (service stabilitrak). Dealership says it has nothing to do with what they did the first time.

Apparently it was the spark plugs and coils, so I replaced all 4 myself.

I ran some fuel injector cleaner through it and it's running much better so I have decided to replace the fuel injectors and the O2 sensors next

CommentSurging @ Idle In Gear Only When Warm
Chevrolet Equinox 2013 FWD 2.4l LEA 179000 miles
I've got a car in the shop currently that is kicking my butt and I could use some input! 2013 Equinox LEA 2.4l FWD 179k miles. This car recently had the motor replaced for broken timing chains that destroyed the head, and then sat for nearly 9 months before it was sold (customer never paid, mechanics lien). It was finally sold and is now back, came in for some unrelated issues (brakes and thermostat) but noticed it during test drives.
The vehicle will surge and misfire badly at idle in gear. It does this under a specific set of conditions, and it takes a while to replicate. Once replicated,… Read complete
