I know i havnt had much time to spend on the site other than ask technical questions, but im starting to get fed up now and need another answer, thanksyou very much to people who reply by the way!

hopefully once its sorted i can get the car up and running and on the road at last! (just gotta sort engine probs then fit all the newly re sprayed body parts)

Car: 95 WRX Import

problem, i had 3 fault codes a while ago which were,
24 Idle air control solenoid
31 Throttle position sensor
45 Pressure sensor / Pressure exchange solenoid valve

but i then took few bits off to paint few bits like the intercooler, inlet (stayed on car), few brackets, and others.

thought id clean the Idle control solenoid inside, thought maybe build up of crud could be causing it to not work,

then took of TPS and just left off for week or so,

then i put it all back together today, intercooler on Idle solenoild on, TPS on, few vacuum hoses re attached,

started the car and it just sits constantly at 2.5k revs, rev it and drops back to 2.5k

also every fault code has disappeared, which obviously isnt right as its not working properly (idle etc) and engine light flashes constantly at the same flash speed (OK code)

anyone got any ideas, atleast when i had fault codes i knew what was wrong,

HUGE thankyou for reading this and hope you can help!

If anyone is local to bedford/ luton way then get in touch as if you can help out! theres all the tea you can drink in it for you! lol

have you set the tps corectly as they need to be bang on to a certain percentage, mine is 6% on secs monitor an wen i adjusted it to 0% it was not good an brought up a cell tell adjusted back to 6%

 

sorry new to scoobys how do you set it? thanks

 

also I unplug the tps and it doesn't change at all, signals broken I guess but no code???

 

Id check the position of the tps. Make sure the spring trigger inside of the tps is on the correct side of the bar inside the throttle body.

Loosen off the screws and try to adjust the tps to see if it makes any difference. When i had a code 24 it was due to my fuelling being a little bit too high on the pressure side but if you have not changed that then rule it out.

Just double check the TPS first as i would say its more than likely to blame.

 

PS code 24 is a few things. But basically indicates an idle system malfunction IIRC

 

i dont think you can set them just like that i think you need some sort of monitor or read out like mappers have or borrow a secs monitor as that reads percentage out on the display, can adjust it by rule of thumb methord to slow it down a bit but needs setting properly imo.....

 

True it would help to have a secs. Thats what i had in the car and the TPS readout was set at 6%. But if it is simply a case of trying to get it to run properly so he can get it to a garage then adjusting it manually till it runs better will be fine.

 

thats all i want, id like i running fairly normal, and sort out what problems i thinki have, then i can take it to a garage for a proper check over,

surely unplugging the tps should make it run even worse? it doesnt do anything?

 

Give me a couple of mins and ill try it on mine as i have just put the ecutek back in. Im just trying to sort a few probs of my own right now.

 

thank you! much appreciated,

 

Hi sorry for the delay. Just unplugged it and it runs fine at idle in the garage.

 

hmmm.... okay, so how should i go about adjusting it? is it just a case of loosen screws on TPS to TB, then a case of twist it until sat at around 1k idle? then do up the screws? sounds to easy like that! lol

 

I would take it off completely and check the metal lug thing is on the correct side of the throttle butterfly first the put it back together. Is there no markings from where the screws were tightened before? If not then just do as you say and adjust it till you have a steady idle speed of about 800rpm

 

shall do that tonight, thanks

as for the lug? the metal semi circle bar which is attached to the T/B butterfly and that goes into the TPS, what you mean check its on the correct side? surely it wont fit into the TPS without going into it properly?

also 1 other problem, sorry guys! but thank you so much for helping, the TPS may be faulty as it did have a fault code for it before, and when ever you used to rev it it would drop to 0revs on the dials but rev fine on the engine, and boost gauge read like -0.9 (idle) then went up where as before all this it was fine (0 - 0.7 bar)

now when it idles at 2.5k lol the boost gauge says about -0.5????? so confused hehe

 

tried it, does absolutley nothing lol

but since then the faults codes have returned, 24 and 31 so i guess that means new TPS and ICS???? or is there anything else to try first?

slightly better now, as in it pulses from 2.5 to 2k revs! lol

any help hugely appreciated!

 

Did you have the throttle body off the car? Maybe the cable is incorrectly adjusted?

 

nope, throttle body stayed on, c able came of but not moved in anyway just took the bracket of that holds it to paint it, the fault codes say ICS and TPS so i now have 2 on the way to me tomorrow so should get them saturday! will let you guys know how it goes? really odd this one?

but thanks for all your help guys! really appreciate it!

 

tps sensor is probably holding the throttle open.. remove the tps and check..

Simon

 

doesnt seem to be doing that, the throttle comes back to stationary by hitting the stop bar on the other side of the T/B, started it then adjusted it, and even pulled it off while running, and it didnt do anything still 2+k???

fault code is for the TPS so i shall have to try another one and see what happenes then, if not im stumped.....

 

also it wouldnt pulse from 2 - 2.5k if its held slightly open would it? surely would just sit at 2 or 2.5?

 

have you removed the top of the idle valve?

if so when refitted the plug faces the front of the car... or it just might need adjustying down.. loosen two screws and rotate anticlockwise.

Simon

 

inlet manifold gasket leaking.

mate had the same thing, would not listen to my advice, started trying to rewire his ecu looking for non existent faults LOL

then realised his inlet manifold was not tight

 

don't think he took inlet off

 

no all i took off was the TPS as it had a code, and the ICV which i need a new gasket for. (one in post with new ICV)

 

inlet stayed on the car! so gasket should and still be fine!

 

I know it is abit of a long shot but I have seen it twice in my time, both on customers cars that had removed the IC.
Both of them had placed tissue inside the throttle body to protect it and keep it clean and had then forgotten to remove it before they put the IC back, basically it was holding open the butterfly and giving very fast tickover speeds.

 

there is your air leak then?

 

Yep as above. You need to put the gasket in to create a tight seal mate.

 

feels fine to me, cant hear a leak, surely that small a leak wouldnt make this big a impact?

forgot to say took vaccum of d/v while running and revs dropped down alot, so it ran better with the air leak. :/ go figure? lol

also to stop dirt getting in the t/b while intercooler was of i covered it up with a spray paint lid, fit perfectly to form a tight seal from any outside dirt etc,
