K, my idle is fucked, it either dies out or idles at fucking 4krpms thats not exagerating, ive replaced the IAC, i am pretty sure its a vacuum leak cuz sometimes its go up and down rapidly ? but i have no clue where to begin. so if anyone could help me, id be willing to fork out some cash to not idle at god damn 4krpms!!

 

might get more help in the tech forum...

 

Give Darren a call ... im sure he can help you out somehow. Or STK CRX - he knows a thing or two about 2.5's

Wow the weekly battles with the MX6 continue. Always something real stupid too.

or ... www.probetalk.com - check there for some advice

 

id call darren but i dont wanna bug him since he lives so far away =/ and ive tried alot of things to fix this but the idle is still retarded haha, anyways thanks ill hit up STK CRX see if he is closer

 

mine used to do the same thing, replaced the TPS, never did it again. Is your check eng. light on?

 

I believe this car has already had that replaced in the last few months (before Darren sold it)

Not sure how educated the new owner is but TPS = Throttle Position Sensor

 

OK i have an mx3, with the 1.8 V6 k series motor. And i ahve the 2.5 klze in it now. (so i know alil bit)

When i use to have idle probs it turn out to be these things:

TPS
Cracked airintake hose
Leaky throttle body gasket
iac
Coolant lines not connected to the throttle body (coolant bypass mod)
stuck throttle cable( stuck liek a milimeter open idles at liek 2000 rpm)
Vacume leakes, but that usually cause ur car to die...
mis adjusted idle screw on the throttle body.
missing fuelinjector sealing ring(caused it to idle craptastic)

 

check the Oxygen sensor, i have the same exact problem with my car and i checked the diagnostics codes, and found that the sensor was bad.
hope that helps ya

 

darren replaced the TPS when he owned it, ive replaced the IAC, had it timed, it did have the coolant mod, got it un bypassed, and it has a Cold air and evertyhing is snug with a new filter,

im thinking vacuum lines, but i guess if that returns notthing ill get new injectors? =/ and i dont think its just my throttle cable because it also dies out, does both =/ oh yeah and it has a brand new TB gasket because i got one when i replaced the IAC... and yes my idle is craptastic

 

hehe thanks
