Clunking sound at the start of acceleration and coming off throttle

[KillinEmSoftly]

I'm getting a brand new noise from the front and seeming left of the car, a sharp sounding clunk clunk when I give it power and one clunk when I come off power. I already have a Vibratechnics passenger and rear motor mount, installed in July. I just got it back from a shop, where they did my timing belt, water pump, and AC compressor. I'm assuming they didn't tighten something properly, but given I don't know what someone would have to undo as part of that work, I can't make any guesses. My first thought is the driver's side motor mount, given which side the sound seems to be coming from and when it happens, but I wouldn't have thought that would have been touched. I'll be checking the easier to access motor mounts ASAP, but I'd love some insight from people who know more than me! Thanks
