Ok, so I have a VDO mini press. gauge hooked up to a T between the filter and fuel rail. It bounces bvery rapidly between like 25-30 psi, and when I pull on the throttle to rev it, it doesn't go up, although maybe it wasn't high enough for boost to come on. Does this sound like a problem to anyone?...

Yup.....a bad coil would cause two cylinders to be dead. I've got the coil on plug set up, so one coil out means one cylinder not firing. But anyway, after many weeks I got the car transported back home where I could finally do some good work on the car. Working on it in dark wintertime on a cold a...

Can you pull the pins out from the back side and clean the connector up at all? Yes, that's quite easily. With a small screwdriver lift the tab a bit on the front of the connector and extract the pin. I was lucky to have similar pins in my stock, so I crimped on a new connector and removed the old ...

Well, some results eventually. After some testing, measuring it eventually proved to be a corroded contact in one of my coil connetctors. For some reason this connector was moist and one of three contacts very corroded. Bummer to see this in such bad shape, but I found the problem and hopefully it w...

I agree with Josh, cyl 3 is dead. Do the easy things first, check for fuel and spark in #3. If good on both then you are looking at an internal issue but hopefully it doesn't get to that. Best of luck, report back with what you find. Removal of the original Legacy coils, removal of the ignitor and ...

I've checked the harness: measuring resistance trigger wires for injector and coil, proved ok. measuring voltage at injector and coil, proved ok, close to battery voltage. measuring ground connection at coil to engine, proved ok (car has WRX coils modification btw) Maybe coil or spark plug is broken...

Sorry Josh for not getting to that point, car developed other problems later on. Been away a lot and also busy on my other Mercedes projects which went perfectly btw, but this Subaru project keeps buggng me...

Dear all, Hope you can give me some input on the following: Recently on my trip to work my car started to run on three cylinders. I needed the car that week so I made a few small trips with it afterwards. It ran most of the time on three cylinders, only around 2200rpm it started to run almost on 4 c...

Today I measured the fuel pressure of my EJ20G; got a Walbro 255 l/hr pump installed. Otherwise standard engine, stock FPR. - installed a t-piece between fuel filter and engine. With green test connectors connected and contact on, measured: - pressure gauge varies with 2 sec. interval from 2,2 bar t...

Quick update, did some testing with the exhaust analyzer today. O2 sensor connected: 3000rpm: 2,5 % CO , 160 ppm HC Idle: 2,6 % CO, 190 ppm HC O2 sensor disconneted: 3000rpm: 2,6 % CO, 95 ppm HC Idle: 2,7 % CO, 150 ppm HC Coolant temp. 85C Two conclusions: - O2 sensor connected or not doesn't make a...

Thanks again Josh for all your help.
I'll continue to do a number of tests here and if I find something I'll of course post it here.

Thanks so far, Bram

Were you able to use the select monitor on a friend's legacy to see how its values compared? No, I haven't tested my select monitor on someone else his Legacy. A friend did test his select monitor on his Legacy I 2.2 and on that car the lambda values were going up and and down and Alpha and Load Da...

I've asked a guy i know who prepares harnesses for people who want to install a legacy engine in there vw or trike and he has confirmed me that the two wires from the temp. sensor go to the ecu and one wire from the thermistor goes to the temp gauge. Anyway, nothing that could be a wiring issue infu...

Oh well, this is indeed a project car with an installed EJ20G. All is/was well, never had any fault codes or funky behaviour, it's still that some of these small issues like lambda value I'd lilke to get working as the manual describes. So far I found nothing in the wiring job I did, and so far can'...

Thanks for your answer and explanation. But I still don't exactly know now how my temp. sensors and gauge should be wired now. Looking at some of the diagrams, you'd only need one sensor then. But why there's two then? From the above diagrams, which one should be correct? This is basicly the only un...

There are two temperature sensors. The brown connector sensor is a two-wire sensor that the ECU uses. There is also a one-wire sensor that is used to display the temperature on the dash. What temperature readings are you seeing at normal operating temperature? Upon idling and some revving without t...

Out of curiousity how old is the coolant temp sensor? When these things go, they typically don't give a code and just feed the ECU incorrect informaiton which will either cause them to run rich or lean. There is A LOT of additional fueling corrections and other stuff that are based upon the engine ...

I did a test session using in total 3 Legacy Turbo ECU 's and two lambda sensors. Basicly came out with more questions than answers. In different combinations it came out that: - lambda value in one combination started at 0,30V and dropped incremently to 0V after say 30 seconds. - other combinations...

You could try resetting the ECU's memory, which should eliminate any past learned values that may be causing you issues. Can you provide a little more information on this statement: Later btw i also noticed my throttle valve was not reaching it 's limits... This I noticed by checking the F10 functi...

Hi josh, Thanks for giving me some feedback and things to go on. Much appreciated on these hard to solve problems! Regarding your last post and questions: Indeed i reported a lousy running engine before, that was however on the previous engine which had some bad compression on two cylinders and a fa...

I bought mine for e 50,- with a few cassettes. There are quite a few Subaru dealer cleaning up their inventory, so many old manuals and tools like select monitor becone available then. As also many people not know what the select monitor is and what you can do with it, you can pick up a nice deal on...

I tried another lambda/o2 sensor. This is a Bosch pn. A24-A71 107 48310 (printed on the shell). The previous old sensor also was a Bosch, pn. A24-631 209 22272. Both these sensors have the correct 4 pin plug with the three wires connected. I assume I got the correct sensor. Anyway, when hooking up t...

Hi, You may want to check out this thread of mine. http://bbs.legacycentral.org/viewtopic.php?f=19&t=24376 Regarding your numbers. The things that stand out to me are the engine load data and the injector pulse width. In my opinion, I'd be suspect of the O2 sensor. Is the O2 sensor you installe...

Good day, This is about some Select Monitor Data that I've collected from my Subaru with 1992 Legacy Turbo 2.0 engine. I've made an overview of all the menu's available, what values I should be getting and in red my actual measured values (ignore these for this problem). All these values are coming ...

I'm assuming since replacing the plug everything was alright? Good advice to start with the basics. Well, I was hoping I found my problem, but looking at the compression test results indicates some more issues with this engine. I guess having only 6 to 7 bar compression on two cilinders explains th...
