Hi Minnet:
This is an update on my car. After I brought my car home from the mechanic (by the way. he was supposed to do a tune-up) I decided to check the spark plugs. Well.....they were clean burned to a gap of .040. So, I replaced the spark plugs with a factory recommended gap of .023. I don't think they have been replace for 2 years. While in the carport it idled for 15 minutes at approx. 600 rpm and for 1 minute at approx 3500 rpm and pumped the gas peddle to make it go from 600 rpm to 1200 rmp for a dozen times. Everything felt smooth and normal. Then I took it for a test drive for approx 10 km including going up a long steep incline and numerous stop lights. All the symptions of stalling and hesitation and jerking disappeared. It appears that new spark plugs have solved the problems. I didn't realize that spark plugs would have such an effect. I will give you an update in a week and let you know how the car is running.
