Take it back to the guys who fixed it, perhaps they've not done the job right. I'd also be tempted to take the map off too if you've thought it's not quite right - it could be doing more harm than good.
I've spoke to the guy about it and he asked that I try and rule out all options before bringing it back to him, he's a friend so I can't exactly start an argument lol. Im jacking up and climbing under etc this morning to see there's nothing obvious going on
