Idles, but dies giving throttle

[mtwebs]

that is a bad rotor from china.
a real rotor CAN NOT TO THAT
it has steal spring clip in the bottom that blocks that (the new car had mitsubishi rotor) and it too does not plant 3ways
the bosch page on same rotor says,"fits just the the original 1 way" they too know what china ,knockoff crap does. what pain.

IAC, the electric one or water only one.?
water IAC is below TB
electric is more front on left side of plenum box, i call it ISC, to make it unique name.

you are on good track for sure... all that.
the high idle.

what is idle with ISC electric connector pulled.
400 is typical or you have air leaks.
sure clean the iSC
make sure the EGRs does not suck air,missing gaskets, are common there.
pinch all vacuum hoses.
IAC stuck open , below Throttle body or the water hose, is blocked
make sure water temp goes to 180f, the IAC closes at 150f so, is 100% closes past 150f.


cold idle is about 1500 rpm and winds down to 800 slow as water gets hotter.
hot is 800. ac off
ac on 1000 hot.

sorry you got ROTOR'ED!
cheers.

Thanks so much for the super quick reply!

ISC is electric. It's off the car now for cleaning. Will check EGR and idle with ISC installed but unplugged wires.

Couldn't find your page on how to clean ISC?

OK - didn't clean ISC (couldn't get tubes to pull out after removing screw) so reinstalled with RTV just to test.

Still high idle unless pinching ISC air hose, *NEW INFORMATION: AND idle drops just fine when ISC wires are unplugged!

I pinched every hose which is visible, without affecting idle speed.

And it still completely dies when opening throttle. It is possible to raise RPMs a bit if throttle is opened a bit, very slowly. But it won't even pull its own weight on level ground.

Just seems like it is not getting needed fuel as it comes off idle.
