I have read all the replies on the post. We have had many ( hard start) problem cars that everyone has gave up on and we get stuck with them. One of the main things that comes to mind on this is how the fuel distributor is set up. Whenever replacing or doing repairs on the fuel distributor you are supposed to set it up , ( setting plunger) It covers it in the bosch cd's and microfiche. I have had many that were not set up correctly (even my own car when I first bought it ) . It will make a differance in how the car starts and also how it runs. This is just a suggestion to what looks like a ongoing problem. If you would like I could fax the procedure. Let me know.
