Retrieve the codes to find out which sensor. Could also be a problem with the fuel system. I had a restriction in mine. A loose piece of plastic was in a new fuel filter (Wal-Mart) that partially blocked the fuel line. The more I applied the throttle, the more it was starved for fuel. You may also check the fuel pump relay under the hood. Verify that the pump itself is working, then follow up the line to the injectors. ALSO, check ignition components. I also had similar symptoms from a bad coil pack. Check for spark.

It is part of the speedometer.
The crankshaft position sensor on a 1987 Chevrolet Celebrity is on the side of the engine nearest the firewall. I need to know which engine to give a more specific answer.
No, the 1983 model does not have a crankshaft position sensor. Only distributorless engine needs a crankshaft position sensor.
The speed sensor on a 1990 Chevy Celebrity is on the top of the transaxle on the passenger side of the car. To change it unlatch and remove the wire harness then remove the two bolts that hold it in. The speed sensor can then be lifted out of the transaxle. To reinstall a new sensor reverse these steps.
The location of the O2 sensor depends on which engine your Chevy Celebrity has. If it is the 2.5L 4 cylinder the O2 sensor is on the front of the exhaust manifold near the exhaust port. If it has the 2.8L V6 the O2 sensor is on the top center of the exhaust manifold near the firewall.
The knock sensor is on the left side of the block below the exhaust manifold.
The throttle position sensor is on the throttle body.
If your 1988 Chevrolet Celebrity has the V6 engine the oxygen sensor is in the middle of the exhaust manifold nearest the firewall. If you have the 4 cylinder engine the oxygen sensor is located in the exhaust manifold just above the exhaust pipe flange.
It on the back of the coil packs going into the side of the block.
Camshaft sensors were not used on any of the Chevy Celebrity 2.5L, 2.8L or 3.1L engines

On a 1985 Chevy Celebrity the mass air flow sensor relay is located on the strut tower on the drivers side of the car. It is behind a cover. The fuse for the mass air flow sensor is also there with the relay.
The oxygen sensor is in the top center of the rear exhaust manifold.
The oxygen sensor is in the middle of the exhaust manifold near the firewall.
According to my factory service manual the throttle position sensor voltage on a Chevrolet Celebrity should be between 0.5 V and 5.0 volts as it moves through its range of motion.
The throttle position sensor is on the throttle body at the end of the throttle shaft.

The knock sensor on a Chevy Celebrity 2.8 L engine from 1987 thru 1990 is located on the back side of the engine(next to the firewall) below the exhaust manifold. There are actually two sensors there, one is the knock sensor, the other is the crankshaft position sensor. The knock sensor is threaded into the block with a pipe thread, the crankshaft position sensor is held in with a 10 mm screw and is near the center of the block. They are both accessible with the engine in the car, but they are a bit of a pain to get to.l
The mass air flow sensor is in the air duct between the air filter canister and the throttle body on the plenum.
The speed sensor is located on the transaxle on the passenger side of the car. It is near the half shaft.
