It sounds like you may be experiencing a partial clog in the hotend. One possible solution is to try a cold pull (also known as "atomic pull"). This involves heating the hotend to the standard printing temperature for PETG, then manually feeding in PLA until it comes out clean. Let it cool down to around 90-100°C, then gently pull out the filament. This method can sometimes help clear out any blockages in the hotend. If that doesn't work, you may need to disassemble the hotend for a more thorough cleaning. Be sure to follow proper safety precautions when working with a heated hotend.
