It might have jumped time.

Could be a dirty fuel inject problem
run the fault code first to check for cam/crank position sensor problems or other electronic faults
and go from there
a dealer charging $80.00/ hr is cheap as where i am it is $145.00 /hr

Please go to the crossfire injection forum to get some straight answers to the 82 corvette CFI system and how to troubleshoot it properly. There's a lot of misinformation given here, so much so, I don't know where to begin.
One thing is, the 82 corvette CFI does NOT have a MassAir Flow sensor system, it uses MAP and O2 mostly. The CTS sends a signal to the ECM telling it what the temp of the motor is and in turn the ECM controls the amount of fuel being dumped. On the older (orignal) CTS sensors, they have one wire and takes its ground from the threads. If any coorosion takes place, usually the CTS will report a cold engine and request lots of fuel.
To repair this issue, install one of the newer style CTS sensors that have two wires, one for signal and the other is ground.
Fuel pressure and vacuum leaks on any CFI motor play key roles. Set the FP to 14-15psi measured inbetween the TBs. The regulator is located on the rear TB and must be slightly moded to make it adjustable and can be done in a few minutes.

That depends on the tariff of the shop. The air con unit needs at most 1.6 liters of fluid and the work needed implies just hooking the refill unit to the aircon and flipping 2 buttons. Between $25 at the local corner repair shop to $500 for an official dealer. Shop for the best offer available.
