If you have a timing light or can borrow one from a friend hook it up and test each wire for fire. Chances your initial problem is the same reason it went to the shop. If you're not getting fire on all plug wires the ignition module could be the problem. Did you drive it to the shop running fine or did all this happen after you picked it up? Why did you have all this work done in the first place?

If it will start with your foot slightly on the gas, you need to clean your throttle body, and possibly replace or reset the idle speed stepper motor.
