Small correction in your otherwise very good post...I think my 2017 Spark LS has 1.4 liter engine. Only issue after driving the new car for 5 months occurs when I am slowing down into 10-15 mph range, and for whatever reason instead of coming to a full stop, I wish to speed up again. If I press the gas pedal hard in that situation to speed up, many times the CVT fails to increase torque ratio. So the car fails to accelerate quickly.
I have found a solution. Simply accelerate gently, instead of stomping on the pedal when car is slowing down in range of 10-15 mph. It seems to give enough time for the software to adjust to the needs of the driver. But I always wait for a good opening before making a left turn in front of oncoming traffic, just to be safe.
Initial car quality is excellent so far. Everything works like it is supposed to, doors close with a solid thunk, all car panels fit nicely, no fluid leaks, tires have not lost psi, no squeaks, no rattles, no parts have failed. That is pretty good for one of the cheapest cars on the market.
I answered my own question. I paid $10 for 24 hours of access to an online 2012 Chevrolet Spark Factory Service Manual at repairprocedures.com
Procedures Valve clearance adjustment (Intake: 0.075 - 0.125mm / Exhaust: 0.245 - 0.295mm) and cylinder head installation and head bolt torque [22 N-m + 82 degrees (16 lb ft + 82 degrees)] were clearly stated.
Greg, you really gave me good reason to think again for switch. I was planning for similar rocker switch for fog install. But will go with push type one.
Just a side by side comparison. I liked rocker in pic as it perfectly match with ice blue backlight on cluster of my beat. So with other one I need to replace LED, its having white backlight.
