Question about 1995 Chevrolet Camaro
Several things can cause this but I would pay close attention to the E/C parameters using a hand held scanner.I would pay close attention to the MAF MAP TEMP TPS and O2 signals the computer is recieving from all the critical outboard sensors providing you are running on all cylinders properly which means all cylinders are pumping up properly and spark is provided at each cylinder.A dead miss can cause an uncontrollable rich mixture.High fuel pressure can cause an uncontrollable rich mixture and obviously faulty injectors which should have about 25 ohms of resistance in the injector winding.Fuel with over 10% alcohol can littlerly melt the electrical windings inside the injector causing fault.Finally I would also inspect EGR which can stick and create the E/C to add fuel to a diluted mixture created from too much EGR (exhaust gas) fed back into the air/fuel mixture....good luck

Seems that the fuel pressure regulator is bad, place a vise on the fuel return hose and if the car runs well replace the pressure regulator.

SOURCE: rough idle stalls at low rpm's
hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck

Timing belt could have skipped a tooth.
Horrible vacuum leak could have started. Listen for suction noises when you raise the hood.
Someone could have poured sugar in your tank.
You could have put diesel in your tank instead of gas.
Could be a bad MAP sensor, TPS sensor, etc.
Need more details to be precise.

Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
