First step is to scan and record codes.
Many AutoZones will do this at no charge.

Assuming your valve cover gaskets were leaking oil that is why they were replaced (which is a common problem for that year and 2000) you have 8 ignition coils that WILL go bad due to the valve cover problem.. l had this happen to mine replaced 3 out of the 8 and sold the car.. The way you are explaining sounds exactly like what happened with mine.. And mind you it is a recurring problem. Have the ignition coils checked almost guarantee that is the problem.
