They probably just dont know what theyre doing and beat on the cars as well.
I drive my DSM daily for 6 years with no idle control. The only thing that really gets me is when the car is cold and I pull up to a stop sign, one out of 10 times it will die out.
500-750 rpms is a HUGE difference than less than 500 rpms, especially when it comes to oil pressure.
And yes, you do drain out little flakes of metal out of your oil every time you change it. What do you think is in your oil filter?
Take a perfectly healthy engine, and cut the oil filter in half. You will all but panic when you see the amount of crap in there the first time.
And to your point, I would be willing to bet that the shorter stroke of the dsm engine plays a major part in that. I had an Ex that drove an eclipse with no IACV. But, they don't need it to idle. On our cars, (KA engines) when the throttle plate is closed, its closed. The only thing keeping the engine idling is the IACV. The glued screw is the idle adjustment. when you take that off and seal up the hole, the engine will die as soon as the throttle body is shut. that's why you have to set your idle off of the throttle cable when you don't have a IACV on a KA.
Also, just to further the point a bit more, watch your RPM gauge closely when you start your engine. I bet it takes less than .5 seconds to get over 500rpms.
A stumbling engine can be below 500 rpms for 1-2 seconds.

that and well, there's a handful of people you DON'T want to contest, you just take as gospel, and Ep is one of them.
thanks man, appreciate it.
And yeah, that's the point I was getting at.
sooner or later I'll figure out how to get my point across without needing a total dissertation.
