subyrally Posted January 20, 2006 Share Posted January 20, 2006 my rx is idleing very high latley when i start it up, it used to only got up to 1700 when cold, not it will run at 2500 rpm until it warms up. then it will come down to between 1700 and 2000 rpm. i cant get the idle anywhere neare where it needs to be without the car being in gear. i tried pinching down the idle air valve hose and there didnt seem to be any change. any ideas or suggestions?

subaru_styles Posted January 20, 2006 Share Posted January 20, 2006 check your coolant temp sensor Quote Link to comment Share on other sites More sharing options...
nkx Posted January 20, 2006 Share Posted January 20, 2006 the buggy does the exact same thing, tim. Quote Link to comment Share on other sites More sharing options...
tizzle Posted January 20, 2006 Share Posted January 20, 2006 If it idles at 1700 warm, I would adjust the idle screw Quote Link to comment Share on other sites More sharing options...
subyrally Posted January 20, 2006 Author Share Posted January 20, 2006 i tried the screw a while back, no change. i need to replace the coolant temp sensor anyways, i already have a new one. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 20, 2006 Share Posted January 20, 2006 check out my permanent fix to the coolant temperature sensor. it's rarely the sensor that is to fault. save yourself money and future issues: http://www.xt6.net/forum/viewtopic.php?t=1767&highlight=coolant+temp Quote Link to comment Share on other sites More sharing options...
subyrally Posted January 20, 2006 Author Share Posted January 20, 2006 thanks gary. ill give that a try if i ever get any free time. i dont know if ill solder the wires to the sensor, but ill us a bunch of dielectric grease and new wiring to the plug.

idosubaru Posted January 20, 2006 Share Posted January 20, 2006 i have one already soldered up ready to go if it's the same as the XT6 (which i think it is). just have to splice it in place. Quote Link to comment Share on other sites More sharing options...
subiemech85 Posted January 20, 2006 Share Posted January 20, 2006 check your throttle cable!! Quote Link to comment Share on other sites More sharing options...
Holmes Posted January 20, 2006 Share Posted January 20, 2006 RallyRuss found a harness to replace the one leading to the coolant thermosensor if that turns out to be the culprit. It's Motormite#85850 (Bosch fuel injection harness). My car has been acting the same way lately. I cleaned my IAC as good as I could without completely removing it and it helped some, but it's still idleing at 1k instead of 7-800 like it used too. I was gonna replace the harness and clean the contacts on the CTS just for the hell of it. It probably won't fix the problem, but it definitely won't hurt.

tizzle Posted January 21, 2006 Share Posted January 21, 2006 i tried the screw a while back, no change. i need to replace the coolant temp sensor anyways, i already have a new one. Are you adjusting the screw on the top, not the one on the side, just want to make sure Quote Link to comment Share on other sites More sharing options...
subyrally Posted January 21, 2006 Author Share Posted January 21, 2006 dont remember what one i turned, but i remember that it didnt go very far and had no difference in the idle. either way, the throttle cable isnt the culprit, its got the full range of movement that it is meant to.

tizzle Posted January 21, 2006 Share Posted January 21, 2006 If you adjust the idle speed screw, facing up on the throttle body, it will definitely effect the idle, there is a smaller screw on the side for fast idle(ie with accessories on) and that will make little to no noticeable difference. I would definitely give that a try Quote Link to comment Share on other sites More sharing options...
Frank B Posted January 21, 2006 Share Posted January 21, 2006 After the car is warmed, check that your throttle cable has just a bit of slack. Also might be an intake gasket leak. Quote Link to comment Share on other sites More sharing options...
subyrally Posted January 21, 2006 Author Share Posted January 21, 2006 ill have to give that a try when i get off of work this afternoon. Quote Link to comment Share on other sites More sharing options...
nkx Posted January 22, 2006 Share Posted January 22, 2006 check your coolant temp sensor i pulled mine out, and the cap was all green and ugly, like a penny after its been in water. the contacts themselves look good. i dont know if it needs to be replaced or not, so i took a pic...

subyrally Posted January 22, 2006 Author Share Posted January 22, 2006 i see that you found it john. try cleaning it up really good and replacing the wires if they are bad, then let us know if that helps. Quote Link to comment Share on other sites More sharing options...
nkx Posted January 22, 2006 Share Posted January 22, 2006 i see that you found it john. try cleaning it up really good and replacing the wires if they are bad, then let us know if that helps. took me long enough too. took forever to find because its kinda hidden, and then i decided i needed to go to sears to get a socket that i didnt need anyway.
