The problem is that you two are right and that Henri is quite agressive. A
computer does not make a car run well if there is no engine, can it ?
My limited experience taught me that a cold engine can vibrate because the
plugs are so worn out that the spark won't be sufficient to ignite a rich
mixture, therefore vibration because only three cylinders run out of four.
After only a few seconds the mixture is better, and after a few minutes the
engine itself has heated up, so the problem is not perceptible anymore. And
this is just one single example to satisfy Dave.
An other one, for and against Henri, is that a computer needs a regular
reset manoeuver because, afer a while, it over calculates the engine data
and gives out wrong information to the electronic commanded components.
Computers are known to crash, even desktop Apples. What makes you think your
car's computer is infaillible ?
And, it would be reasonnable to assume that a 97K miles car is not brand
new anymore and that noises and light changes in car behaviour are possible
due to general wear and tear.
Personnaly, I would think that Dave is right, because it is such common
sense.
