But the fact of the matter is that engineers with mechanics-like-thinking are who get the job of designing the engine.
And I am not one of them.
I simply oversee these kind of guys.

you're not helping us help you by arguing with your silly bullshit "logics" which are just symptom descriptions and claiming you are an "engr" and still don't sound like one
let me say again.. if you say you know what the problem is... which you SAY is the engine.. how come you're here right now asking *us* what the problem is?

If I remember correctly , I specifically asked for how to richen the mixture.

wow you guys type fast. another question (in addition to the one above!)
Did they give you a reason why they can't richen the fuel mixture?

Later on, they changed the design to a 2.0L.

did you take the 10 day video courses that you can buy off of TV infomercials? you... you don't know ****, like a bore from a stroke so you just "leave this kind of talk/calc for just out of college grads"

But I was more intrigued to find a solution to this problem and was expecting some good responses from this great crowd over here.

Ask Jerry Standefer (Jstand6) from California.
He lost quite a few sale of the ES when he was selling Mazdas at John Hines Mazda just because customers felt this jerking/jolting when taking test drives.

Do you know how a torque converter works and how it could affect idling and take off? since you THINK that richening mixture is the end-to-be-all solution and that the engine is the problem and NOT externally related issues, why don't you have a mechanic *try* it (and fail) and watch your engine stall IF your "mechanic" was able to richen the fuel ratio at all?

I have a 99 ES with 50,000 miles on it.
Ever since I got it, it has had a problem of having an extremely lean mixture at idle. I believe all the 99-00 models having 1.8L engine have this situation. The lean mixture by itself is not a problem.
The problem is that at idle the engine almost stalls when the A/C engages and you happen to have your headlights on, brake lights on, and the radiator Fan is running. This is a typical situation on a summer night.
Due to the "almost stall" phenomenon, I can feel a jerk/jolt in the cabin as the engine recuperates due to the increase in idle speed signal sent out by the computer. But that signal is a feedback signal, not a proactive signal.
Is there any way the air flow mixture setting can be changed to be a little more rich at idle so as to be able to take the extra load?

Keep in mind that the engine has been tuned by Mazda dealers( 2 of them), checked out by the Mazda Reps, changed ignition coils, the refrigerant checked out.
