Hello Vicfan and welcome to Just answer.com, Super mechanic here. About your Achieva.

Do you know what the compression is?

Do you know what the fuel pressure is?

Can you check the injector pulse?

The compression and fuel pressure were tested about 3 months ago and tested fine, I dont know any of the numbers. I can listen to the injectors and see if they are all working... At the same time the fuel pressure and compression was checked the coil cover was replaced because of this same problem, the car ran perfect for a few weeks and then started hesitating and eventually stalling again.

There is a way to check them but you would have to make 4 wires to go to the plugs from the coils.

You would want to make sure that it is not loosing spark to any of the cylinders. There may be a problem with the module. As long as the injetors are good and compression is good, I have found that either the coils, cover, or module are where the problem lies.
