Why would tapping on a Cavalier coil assembly make it run fine when otherwise it stutters and misses and does not want to start or run correctly?

Replace the coil pack. You can buy this part at any auto part

store and have a nechanic put it in for you or do it yourself if

yer feelin froggy but you need a new coil assembly or new wiring

and connection to it. you can also probably find a good coil

assembly from a junkyard as these usually outlast the cars the

reason it works when you tap on it is the coils are burining out

from the inside and losing their connection. When you tap on it you

cause the vibration to make the coils hit a "hot spot" as

electricians call it. anyway replace the coil assembly.
