Well the problem first started about a year ago. My tach would jump all over the place after about 5k rpm. I replaced the Ignitor and the car has been fine ever since. Well about a couple of weeks ago the car started dying out while driving. Well I figured out the problem and It was the Ignition Coil. So I replaced that. Now about a week or 2 later it starts to spike around 4.5k rpm. Since the Ignition Coil is new and Igniter is about a year old, What else could cause the rpm gauge to flip out?? When the car has been runned for a while it will miss a lot when the RPM gauge flips out. The Cap and rotor has about 12,000 miles on it. Could the bad contact on the cap and rotor be a problem??If anyone else has a recommendation please let me know 
Thank you …
