The 1988 Chevy Celebrity uses distributorless ignition. There is no provision to alter timing, the engine control module takes care of that.
The 1990 Chevy Celebrity engine is distributorless, the ignition is handled by a combination of the engine control module(computer) and the ignition control module. You did not mention which engine the car has. If your car has the 4 cylinder engine the ignition control module is below the intake manifold at the rear of the engine. You can follow the spark plug wires to it. The coils are mounted to the ignition control module. If your car has the V6 the ignition control module is near the starter and again you can follow the spark plug wires to it. Again the coils are mounted to the ignition control module.
Timing on a 1987 thru 1990 Chevy Celebrity 2.8/3.1 engine is controlled by the ignition control module along with the engine control module. There is no provision or specification for manually adjusting the timing on these distributor-less models.
Assuming you have a mpfi engine it is in the throttle body.
I would suspect a failing ignition control module.
