GMC Canyon engine cuts out while driving and stopping on GMC Canyon

Some GMC Canyon owners report experiencing engine cut-outs while driving and stopping, which may be attributed to several underlying issues. These include carbon build-up on the intake valves, which can lead to reduced power and performance. Additionally, improper engine timing has been linked to stalling and misfiring, contributing to poor engine operation. Owners of models from 2017 to 2019 have also reported transmission problems, characterized by a noticeable shudder from the 8-speed transmission. Furthermore, a malfunctioning actuator may prevent the engine from receiving the correct signal for idling speed, resulting in engine cut-outs. To mitigate these issues, it is advisable to clean the intake valves, check and adjust the engine timing, address any transmission concerns, and inspect or replace a faulty actuator.
