Funny Idle after timing belt change??

[rmenaul]

I got my timing belt changed, and since the car seems to idle funny. I have a 1995 Eagle Talon TSi, and the guy who changed the belt doesn't seem to notice or know why the problem arised... what could cause the car to idle poorly since the timing belt change???

Incorrect timing. Check the marks.
