I cleared the check engine light and went back in and they got it programmed. When I told the tech what the guy said the day before about the CEL, he gave me a quizzical look as if to say "really?...sounds like that guy didn't know what he was doing". So, I don't know if it actually was the CEL or if the tech just didn't know what he was doing or a combination of both. Either way, problem solved!
