Do you have to remove engine in a 97 gmc sonoma with 2.2 4 cylinder change oil pan gasket?

No, you generally do not have to remove the engine from a 1997 GMC Sonoma with a 2.2L 4-cylinder to replace the oil pan gasket. The oil pan is accessible from underneath the vehicle. However, it's a somewhat involved job requiring the removal of the oil pan itself, which involves dropping the oil pan, disconnecting various components (like the oil filter, potentially some exhaust components depending on interference), and cleaning the mating surfaces very thoroughly before reinstalling the new gasket and pan.
