Well the biggest problem with my car has finally been fixed! I have finally got around to properly cleaning the IACV. I left it in a container of petrol for a few hours, then used ear buds to start scraping off the dirt and grime inside. The previous method of using carby cleaner didn't do anything....

Yeah the engine throws a bunch of codes. The only one I can get from the car myself is code 24, for the IACV, this is most likely the cause because the CEL would come on regularly. The mechanic I go to used his fault code reader and pulled out these ones: Parking position switch (I heard this is onl...

Would you know what kind of spray I can use to clean the thermocouple? Also, is the screw part of the thermocouple meant to be that loose?

Okay I think I found it. This one has a 3-pin connector. I wont be able to find the one near the catalytic converter until I jack the car up.

From this diagram here: http://www.ellisfamilyalbum.com/Car%20S ... iagram.jpg it seems that the sensor is meant to be in the up-pipe. I don't know which model WRX this diagram is of though.

Yeah, it was in the large pipe, leading under the car, right after the turbo. After looking at pictures of thermocouples, it looks much more like them than an oxygen sensor. This sensor has a 2-pin connector, if that helps. Is it possible this sensor is in the wrong place?

I have found a "neutral position switch" in the car manual, connected to the "ECM" however this is not one of the fault codes. My car shows me 2 CEL codes and my mechanic used his very expensive fault code reader to pull out 7. The oxygen sensor is one of them. I pulled it out and took a photo. It l...

Ah okay, thanks. My car is having some VERY bad idle issues. The idle is fluctuating all the time at about 1,500k rpm. The O2 sensor is in pretty bad shape so I am guessing that it causing it.

I have a good felling that my oxygen sensor is failing. I can move it in and out of the exhaust about a cm without loosening it. I have located one that is at the start of the exhaust, right after the turbo, but I am not sure if there is another one. Anyone know? I can't find an answer on the intere...

Hi everyone. Do any of you guys know where I can find an IACV gasket and maybe a throttle body gasket? Can't seem to find them on the internet.

Thanks. I will look up how to check out the clutch system. Maybe I do have a button clutch but it has been worn so bad that it engages nice and smoothly ;) The crunch in reverse is most likely due to the gears still spinning due to the car still rolling. I always have the car at a full stop when I t...

Hi everyone. As some of you may know, I have a '93 WRX (conversion). When I bought the car the seller said it recently got a new heavy duty button clutch, however I am now experiencing symptoms of clutch slippage which indicates an old, worn out clutch. Just today, when I entered the freeway, as usu...

I will try this tomorrow morning and see if it makes any difference. So I removed the connector going into the MAF sensor and stated the car. As usual the car revved up to about 2,300 for a couple seconds then dropped to about 1,500 and stayed there like it has the last few days. As I tried reversi...

Unplug the air flow sensor and drive with it disconnected, generaly it uses heaps of fuel, but runs ok. This tends to be more noticable in stop/start traffic. If it idles/drives slowly ok all the time, it may not be the MAF. I will try this tomorrow morning and see if it makes any difference. Looki...

If I take apart the throttle body and IACV I need a new gasket right? Does anyone know where I can get one? The ones on eBay are all the way in the United States!

Do I need "Throttle body cleaner" to clean out the IACV? I am also going to clean out the MAF sensor. Is there any way to check for codes even though the diagnostic plug isn't there? Edit: I just opened up my air filter and took a couple photos of the MAF sensor. Does it look like it needs cleaning?...

Well it seems that the ECU wasn't the problem The day after I reset it, the car seemed to drive perfectly. 1,700 rpm was the highest it reached when I first started it. But this morning the engine "choked" on me...

Okay so I reset the ECU, well at least I think I did. Is there any way to prove it? I drove the car for a bit afterwards and it seems to drive a little smoother now. Or it could be just a placebo effect :) I will test the car on Tuesday morning when I head off to school and see if it idles to 2,300 ...

I am going to leave the battery disconnected tonight. I also have to leave the car idling for how long tomorrow?

The engine is an EJ20 turbo. I couldn't clean the throttle body as I we didn't have any throttle body cleaner. I went over the notes they wrote when they serviced the car a week or so ago. In the notes they said they already cleaned the throttle body. They didn't say anything about the IACV though.
