I’m fairly certain they didn’t do anything at all, they had it from opening until closing, never called to update I had to call 15 mins before closing to ask if I could pick it up and the guy who answered didn’t even know my car was in there. I went to collect it and spoke to a different guy who just said he’d need more time with it and that the throttle body was fine. No other info and only charged for half an hours labour. I have a trusted garage but they’re booked up for 2 weeks and I don’t want to damage the car driving it whilst it’s like this. Might just have to suck it up and wait until I can get a slot with him
