Firstly hello to everyone and congratulations on an excellent site.......

i have just purchased an s-reg classic impreza wrx in green,

it has had some work done to it including a HUGE front mount intercooler,
full stainless cat back exhaust, induction kit and other mods i have not even discovered yet lol.....

anyways, the car had just had an engine change and in the boot i found the old throttle body, injection manifold and injectors and the idle controll valve.
the old throttle body had a seperate hole in the manifold for the idle control valve ( which is a 3 wire connector). the new manifold thats fitted to the car has no seperate hole for the idle control valve, instead it is a 6 pin connector and the idle control valve is mounted on the throttle body itself.

is there any way to convert a 3 pin connector into a 6 pin connector? the car is idling poorly until its warm (understandibly)

also the temperature gauge is not working but is connected engine end and i removed and refitted the connectors at the cluster end just incase it was a faulty connection.

finally the speedo isnt working properly , instead it either does not work at all or acually works backwards..... ie: i do 30 mph and the clock reads 120mph, as i slow down it reads a faster speed until finally it rests at the 6 o'clock position which is where it stays when the car is stationary.

any help would be muchly appreciated guys, i want my scooby running right asap lol

 

update.......

speedo seems to be working again now but still no temp gauge working :0(

 

Back to the drawing board again.....
Speedo did a full turn on boost in 3rd and now sits the wrong side of the needle rest and stopped working again.

Located an injection manifold with everything I needed, stripped old manifold off to find out the location of the bolts is different. The engine fitted has the bolts at a diagonal mounting and the new one has str8 mounting points so won't fit.
Problem is that I now believe the engine to be from a newer car which is why the wrong connector is on the loom(3 pin) for idle control valve. And the actual idle control valve on the car is a six pin..... Not sure I can remedy this...
Any help would be much appreciated guys

 

we have a number of manifold laying around and could check out your other faults if that helps.

 

i also have the same problem the idle control valve on the car is 6 pin but the wire harnness has a 3 pin plug on it is there anyway to convert it over

i also have an other maniflod sitting about but the bolt holes done line up

 

Poor idling could be the ICV or MAF-related.

I assume the car HAS had a remap after all those changes?
I thought the 98 ecu's couldn't be mapped, maybe the WRX import is different?
