Stalling during first fifteen minutes

[mrlmd1]

ER - I have to differ with you on this, and yank your chain a little.
AC said his idle speed was lower now than what he remembered before, but it's running fine and doesn't stall. Without a tach or some way to measure the rpm, you are relying on HIS perception of what the idle speed should be, which may be quite inaccurate. It might be set to the correct rpm by the shop. All of what you said may be true but not applicable to AC now. He's not stalling, not complaining of difficulty starting out in 1st gear, no problem with shifting, but you are relying on his perception that the speed is too low (which may be untrue) and telling him to bump up the idle speed with the big white knob? And how much, or how many rpm, is a tad? And how is that measured?
I don't buy that, at least without knowing what the idle rpm is, if he's not having any problems. Maybe now he's used to hearing the Strat which I'm sure has a totally different idle sound than the GZ, but why screw with it if it's running perfectly fine? Is a little higher idle speed better? Then why aren't they recommended to be set that way, and wouldn't even a little more be better still? :??: O_o

And, to your previous question - if it comes back worse, you bring it back again, just like AC did, and again, until it gets fixed to your satisfaction. Or complain to the manufacturer, then you'll get it fixed.
