Thanks for your help. I will try to get answers to your questions by tomorrow.
The distributor was replaced.
There no codes stored in the computer. However, the check engine light is still on.
Thanks for any help you can give.
Raymond, my mechanic check for the codes using his $800 hand held testing unit. He said that there were no codes stored in the car's computer. He said that that means the problem is probably not electrical. He has replaced everything he thought might be the problem starting with replacing the fuel filter in the gas tank.
If you have any other suggestions, he will work on the car on Monday.
The only clue I have noticed is that when it begins to jerk or cut out I can stop the jerking by putting the clutch in. .
