2004 Mach 1 Hesitating - 2003-04 Mach 1 Registry Owners Club

A few weeks ago I noticed a slight hesitation under low RPM's while accelerating. The problem slowly started getting worse so I took it to my mechanic. He said he thought one of the cylinders was missing, but since the check engine light was not on, the computer would not tell him which cylinder was misfiring. The problem has gotten much worse and the check engine light is still not coming on. It is now hesitating throughout the RMP range and is very noticeable. Any ideas of what the problem could be?
