I would suspect a vacuum leak on a 20 year old car. I would recommend you replace all under hood vacuum hoses. Do them one at a time as to not get confused. Also check the hose going to the brake booster. Of course it can be other things but this is a good start in eliminating possible issues.

If your Corvette has the LT1 engine then it likely has a problem with the Opti-Spark distributor. These are a notorious problem with the LT1. It is mounted on the water pump and when that water pump seal starts to leak it leaks into the distributor housing causing condensation. Search the web for the various kits that fix this issue. there are several web sites that discuss the Opti-Spark and how to upgrade.

Rough idle


The cam or crank sensor is going out when driving at high speeds. I would have those parts check, and have the fuel pressure check , fuel filter change to be on the safe side.

Good luck
