94' Chevy S10 Idle Problem after Maintenance

Hi, I recently took my truck in to have the spark plugs, rotor, and distributor cap replaced, and afterwards my vehicle has a very rough/lopey idle as well as a low idle rpm. Basically it runs worse than when I took it in. I double checked the spark plug firing order and distributor cap order and they are all hooked up properly yet I still have the aformentioned problems. This is my daily driver and I need to get it smogged really soon, so if anyone has any idea as to what may be causing these isues, then that would be greatly appreciated. Thank you

I would take it back and ask them to check it out on there dime.
Most good repair shops stand behind there work and if it is not right you should let them know about it and give them a chance to correct the problem.
