Engine finally runs OK, but no real power!
#8
Thank you kindly for your reply FIXKICK.

1. As I had reported earlier (I know you are not expected to remember everything I have written in past 4 weeks), the engine compression are uniform and, as far as I am concerned, excellent. They are all at 155 psi at cold wide-open cranking.
2. The engine light goes off after a few second upon ignition, and I get code 12 - no problem at all.
3. The spark plugs are black and dry.
4. The fuel pressure should be tested.

QUESTIONS:
1. How do I check the vacuum (at what location/what hose)?
2. Why is it that as soon as I put it in gear it dies; even if the cylinder compression was the issue (which is definitely not in my case)?

Thanks again!
Zackman.

Another point I should mention. I have noticed that the plunger retracts immediately when the car is cold and started. In past, it used to stay on for a few second, then retract and let the RPM go down. Would that serve as a hint?!
