Question

Changed map sensor & still rough idle & truck stalls

Answer 1

The 2005 GMC canyon as 2 major issue when it comes to rough idle, first one is the Camshaft position actuator, this has a high tendency to plug up and create a rough idle and misfire this is due to oil maintance.,,pull the camshaft actuator out clean it with brake cleaner or carburrator cleaner,then reinstall, if this does not solve you need to inspect the ignition coils for especially the sparkplug boot for traces of spark voltage arking to ground,
