If its a 93, It probably is a CPI motor.
Yes the fuel regulator. If you pull the cover on the intake and its clean then you have a fuel leak. Youll notice it in the mileage. I dont remember the part number but you can get em a NAPA and they come with the security torx bit. This is a common problem with the CPI, and might as well just get a new one before you tear into it. Not a big deal, like $40 bucks. Heres a write-up.
