its a LOW TIRE PRESSURE WARNING SYSTEM is ran buy a sensor in each rim and a modual under the dash....

The distributors give this vehicle a lot of problems,because of the location of the distributor,The cause of your problem is,no injector pulse,most likely,you will have to replace the pickup coil in the distributor,and my advise,is to replace the pickup coil,module,and cap,and rotor.The reason being,is that it is an act of congress to just replace one of these,because of the location of the distributor.The water pump needs to be checked also,it can leak on the distributor,and cause a lot of problems.The parts will be high,but better to replace it now,all at once,and be done with it.The cap,and rotor are only available in a kit.

Check your radiator fan is cutting in when it's supposed too Sounds like that the cause is no air flow when you stopped or in slow traffic

The A/C system has a pressure sensor that detects the freon level in the system. If you lost freon, the clutch that engages the compressor will not engage. A good indicator is to turn on the A/C and watch the compressor/clutch assembly. If the pulley is spinning and the clutch is not, odds are you have a freon leak. Good luck!!

After opening this link go to answer #4 for a breakdown of your engine,of coarse included is your firing order and plug locations.Take care!

check plug wires , plugs , and cap and rotor

cap is not fun on this one , best done by a
proffesional

Has the Optispark distributor cap been replaced yet, if not have it replaced.

Thier are two fuse panels on the 93 corvette. One is under the hood near the battery and one is on the passenger side in the crevis of the door. you can only see it (on the side of the dash) with the passenger door open. There should be a twist knob on it.

from the service manual.
Connecting rod nuts, tighten evenly to 20 ft pounds then turn another 55 degrees of rotation, seems odd but i have the factory manual

what trouble codes do u have?, here is how you do the test. Go to the link

Hi
Thanks for using FixYa. The stall is likely caused by either a problem in the electrical system or in the fuel system. Your engine stops running because it is not igniting gas in the cylinders, this occurs either because there isn't gas to ignite, or because it lacks the electrical charge to ignite it. Drive the car up and down steep hills. Does this change the performance of the engine, or cause it to stall? This might indicate a clogged fuel filter. Replacing the fuel filter is relatively cheap and easy. The fuel feed line is pressurized by the fuel pumps/sender unit so with engine off line is depressurized.

Please check the procedure for filter removal/replacement--

• Any time working with the fuel system always disconnect the battery... unfortunately you will loose any stored stereo stations.

• Loosen fuel filler cap to depressurize the fuel tank (a put a note to remind yourself to tighten back when you finish everything

• Go to fuel rail (right side) uncap shrader valve, place a paper towl under and in front of it and then simply push in valve stem and depressurize the fuel rail...you will get about a oz of fuel squirted out. Replace shrader valve cap immediately.

• Get a plastic container as one you would use to drain engine oil...put some paper towls in it (keeps the fuel splashing to minimum)

• With a 10mm socket remove metal shield protecting the fuel lines/fuel filter..with same socket remove bolt holding fuel filter to frame

• With a 17 mm and 21 mm (comparable non metric work too) loosen fuel line from fuel tank at filter and just let drain for couple minutes (it doesn't gush out more a a dribble)

• Pull slightly the fuel filter to totally disengage from tank fuel line

• Now using same 17 mm & 21 mm wrenches remove fuel filter from fuel feed line going to fuel rail..

• Basically just reverse to procedure to install new fuel filter...

(1) Inspect the fuel line connector O rings to make sure they are in good condition,
(2) make sure you reinstall the fuel filter retaining band around new fuel filter first (but can be bolted back onto the frame rail last),
(3) make sure to install new filter with the flow going in the correct direction and
(4) I do this just as a precaution.. Use Lock tight blue on the fuel lines to filter connector threads (they only need to be tighten to 22 lbs so don't go garage ape on tightening them.

• Reinstall the shield

For removing the filter you will also need 16mm and 20mm wrenches, and flare nut, crow foot wrenches.

Does the car idle roughly and stall when at idle? Your car has a distributor; you may need to adjust the timing. With the right tools and know how, this is an easy and free task. you might consider changing the cap, rotor, wires and plugs. This is effectively a tune up and will resolve your issue.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

By chance there may be something protruding that keeps it from "Opening its eye." Check carefully or it may just need a shot of WD 40. Good Luck

You may need to charge it up with freon at a mechanic. After a while your ac runs out of freon and needs to be refilled.

Are you talking about the A/C clutch?No clutch engagement usually means no refrigerant in the system....or not enough to allow the pressure switch in the system to close allowing power to the A/C compressor clutch.
This is the problem 99% of the time there is no A/C clutch engagement.The other 1% is electrical....burnt out clutch windings or no power to the system.....fuse etc.

Have the antenna motor tested re place it if not working if antenna motor is working you will need a new antenna mast and antenna cable to remove this unscrew the washer nut at the base of the antenna and turn radio on antenna should push up and play out he cable to replace insert new cable and turn radio off it will draw cable in and antenna tighten washer nut and your dne

could be faulty control panel of the stereo. Otherwise, it may have a bad fuse or fuse that is going bad. Last cause would be a faulty wire. Most likely control panel if it is getting power but not showing the display

The cooling fan relays are located on the upper radiator support in front of the left front wheelhouse.

you have 2 relays for your fan, primary and secondary
their controled by the PCM according to the temperature
