That is helpful as from memory im sure there is a 2 pin thermistor on the front of the engine and the 3 wire one the back, i would have guessed it was the front one, are there many people on here with legacy gts? Theres only 3 in my town, one i sold to my mechanic, one i sold too his friend and mine, bit of a sleeper when they work ;)

That link has helped me a lot, its refreshing too have genuine help and not people lecturing me on buying an import :) embarassingly i dont know where the engine temp sensor is, even though ive had the engine out and rebuilt it,ha, thanks again

So... Back at the car, starts ok, runs for a few mins, then once its warm the promlem occurs, unplug mafs and it dies, unplug the throttle sensor and it revs then dies, O2 sensor has little effect, but once the engine is warm it wont run for long before it dies,is the an engine temp sensor, i know theres one for the water temp gauge but not sure if its the only one, also can the engine temp somehow effect the idle revs??

I will try some injector cleaner, but as,im unable too move the car it may take a while too have an effect, it may be the mafs, is there any way too check them? Will also study the cars history, it was doing this before i started too work on it and is mentioned in the service history that came with it, so its either been an intermittant fault or the previous owner just put up with it, the legacy is a good all rounder, 280bhp standard, plenty of kit in the spec, large, good cruiser, big boot, mines got bilstein suspension aswel, but not as fun as the impreza, is a point between 4000 and 4600 rpm where the primary turbo drops out and they both cut in again, which when booting it is a pain, but i had too get rid of the impreza as it was too small, the legacy was a good excuse too get another subaru, was very happy when i found out they did a twin turbo, hope i can get it sorted, is a rare one as its uk registered and driven around and used from 2000 to 2003 by pro drive execs and the subaru rally team

The engine check light isnt on, im not sure where the similarities end between the impreza and legacy? I did own a 2005 wrx estate (hatch) dumbest thing i ever did was get rid of it, im on my 3rd legacy gt, so much car for such a small amount, my 1995 manual one was the best car ive ever owned, cost me 700 and never went wrong, they have a self diagnostic and will give out fault codes, theres none present for the erratic idle, im wondering if its an injector, coil pack or plug as the engine wobbles most the time its running, trying to avoid paying for help as im over budget already, will remove the coil packs and check for a spark, not sure how too test an injector though, wish id done a single turbo conversion now, will keep my findings posted, thanks again for your help

Hello, thanks for the kind welcome and a reply, ive tried too look for an air leak, i use leak sprays at work so tried that and couldnt find anything, would the leak have too be between the throttle and the engine intake or could it be anywhere between the air filter and intake?? The engine will start ok and run till it warms up and the revs drop, but the engine does have a bit of a wobble as it idles around 1000 rpm, and i did the clutch myself, my boy brought the car off ebay for 450 with big end failure, so took it on as a project, and changed the clutch while it was out, the existing one was the wrong size and had worn against the flywheel bolts, after much research i sourced the right one and installed it, may have too take the box off once i sort the engine, was hoping i wouldnt have too but dont think i can avoid it

Hi guys,new to your site, after some technical help and advice, ive just finished rebuilding a 2000 subaru legacy gt, although the logbook doesnt say its imported i know it is (prodrive imported it from the factory in japan from new) making help and advice hard too get, mainly as its a twin turbo, two problems im have,first is the clutch is stuck, it was put on new on the first of jan this year and been sat outside since, is it possible for a new clutch too stick to a flywheel, if so is it possible too free it? And secondly once the engine runs and warms up it runs erratically, revs up and down then cuts out, also wobbles like its running on 3 cylinders, its an ej20 but has individual coil packs, am not a mechanic but its my 3rd legacy gt and 4th subaru so im gettin an understanding of what and how they work, any help is hugely appreciated
