I like you as a person, but I dont agree with your statements.

1) Selection of Oil really does make a difference.I dont want to get into tribology and oil science, but some oils do leave a film taht lasts just a bit longer and is thicker after the oil level itself is gone. I don think this is an old wive's tail, its a new wive's tail because in the 21st century, there are more women in management than men...now wait until they start tinkering under the hood..

2) The injector problem is unrelated to the Breather Tube mishap. It had to do with my original loss of power when I started to mess with the car to begin with. When I described my cold start problems, he queried me about my injector lifespan

3) The engine miss is also unrelated to the cold start problem.
It was there before the breather problem and its the reason why I messed with the filters (fuel).

4) I RESPECT any guy who has been doing this stuff for 20 years,
and I do believe he is correct.
