So 2014 glk 250 threw up p261f code AGAIN after the water pump was done, along with the entire vacuum system, etc.. it also seems to be idling a little rough, but other wise drives really nice. Starting to get pissed at the shop who’s worked on it seems like they don’t know what they’re doing. Anything else that could cause this code? I cleared it and it didn’t come back after a 15 minute drive but still idles rough a bit. And when I turn the car off it sounds like some pumps are trying to actuate or something (could slightly hear it when on as well)
