Car Idles at 2000 RPM!!! Please advise.

[CMF_BeeBoop]

Hello,
My little Machine (95 SLX) has only been on the road less than two weeks now. It already has a brand new throttle body / mass air-flow meter. When i first installed it the car idled PERFECTLY! Now it wants to idle at two grand! I am fairly sure that it has something to do with fuel, as i am on my third fuel filter in less than a week. (had some rusty junk in the tank that was blocking the filter and causing the car to stall). So has some rubbish gotten past the filter perhaps? Do i need to clean out the fuel rail? Let me know what you think. Any help is greatly appreciated.

maybe the coldstart waxstat at the back of the t/b is stuck on beeboop ? or idle control valve ?
and how has rust appeared inside a plastic tank ?

 

[CMF_mycra]

idle control valve, throttle body coolent lines check for leaks or blockage, doubt its the idle adjuster.

Hello. Well this issue hasn't resolved itself, so what should I do people? Please help! It is so stressful having the car constantly idle at 2000 RPM! I checked the coolant lines and blew them out with compressed air, so shouldn't be any blockages there. I unplugged the little sensors on the throttle body and sprayed them with WD40 and I'm pretty sure it fixed the issue for like two hours! Help...:$

 

[CMF_frank2]

it sounds like the idle control valve beeboop (on the front of the t/b)
have you removed it and cleaned it ?

 

[CMF_BeeBoop]

Nope. But it won't like spring apart on me will it?

no mate but you have to make sure the O ring inside it is seated properly when you refit it tho, and grease it too

 

[CMF_BeeBoop]

Sweet as! That's my mission for tomorrow then. Thanks again!

 

[CMF_frank2]

np
you could access that it is at fault if you shove something down the i/c/v apperture and block the port (the idle should be very low then)

Legend! Thanks Buddy.

Frank.... Will you marry me and have my babies???
It's FIXED! Totally was the problem. Perhaps my new icv was damaged when i pressure washed the engine, because i removed it, cleaned it, and put it back in but it was still idling at 2000rpm! So i removed the old one from the original throttle body and did the same, and now the car idles at 1100rpm. Which i sooo much better, i don't think i would want it any lower than that because when the air-con compressor engages it drops the revs by around 500rpm. This normal???

that actually how i stuffed mine the first time...i can tell you that o ring is pretty hard to find..i had to take it to a engine builder to get it..get a new o ring and you can drop the idle to 6-700.

 

[CMF_mipcar]

Yeah, that ring seems to be an odd size. Hard to match the size and profile.. Maybe Nick (NSM) should get some in.

 

[CMF_frank2]

lol beeboop
it might be worth trying a different idle setting eh (1/2 a turn in, on the plastic allenkey screw on the rear corner of the t/b should drop it a tad)

 

[CMF_mycra]

only makes like 500 more or less difference... best way was is to get from another cg13, ga15 and ga16.

i actually went to nissan for that o ring the first time, they told me to buy the whole throttlebody... pricks.
