Hello,
i'm from the dutch mx-3 community and i have a problem that i dont get fixed.
everytime when i hit the trohtle my idle speed hangs a few seconds on 1500 rpm.
also when ten en grnd where connected. here you see it yourself:http://www.youtube.com/watch?v=cGKyWYLXoMk

now i've adjusted my tps and set him to recommend settings, just like the FAQ @ this forum.
Now when i connect ten en grnd my idle speed goes to normal value.
but when they are not connected the problems is still there.
i hope you can help me.

kick...

sorry dude, don't know how to help, but I have to say, I like your gauges. Where did you get them? Back to the problem? could the sensor be bad? but I really don't know

man those are some amazing gauges haha. hmm have you checked the car for codes? hmm maybe a IAC vale sticking and then closing not too sure. what engine are you running? dual overhead cam or single?

I would suggest cleaning the idle air control valve where the coolant passes through. It gets very dirty in there and could be causing the valve to stick open for a second.

does v6 have same valve? I have same problem with idle sticking at 1200-1500rpm. Ive noticed though when car is stopped on a hill it will idle normally at ~600rpm

hey,
the gauges are from poland. We had a groupbuy with the dutch community.
I run a 1.6 dohc. I have cleaned the IAC. But the funny thing is.. when ten and ground are connected he runs normally.
and when is @ 1500 rpm and i set the airco in, he falls back to 750 rpm.

Replace the TB with a known good unit from one of your friend's cars if you have one and see if it goes away. If it's not a sensor or a TB issue it could be mechanical like something obstructing the throttle cable.

ok i will try...

maybe try cleaning out your TB real good.

i've done that with no result...
next weak i gonna change my TB with that from a friend.

my car used to do the same thing, it got so bad that it would no longer idle under 1500. I just replaced the whole tb with the sensors and the idle motor. I had no problems after, good luck.

Btw i too love the gauges

I found similar gauges on ebay in MPH Should be coming in today or tomorrow.
