2014 Spark LS, Manual Transmission - 101K Miles
Driving vehicle, Speedometer stops working, Fuel Gauge becomes erratic. Pulled over, turned vehicle off and on again. CEL never illuminated.
Gauges then started working properly, but the car would hesitate upon hitting 4000 RPM in any gear. Cautiously drove another ~20 minutes. Near the end of the trip the hesitation issues stopped.
I am absolutely super confused. At first I thought it was a cluster issue, then the bogging made me think engine issue. All combined I am wondering if something is up with the ECU.
