Re: Weird power loss at high speed...(troubleshooting)

Thanks for your thoughts so far guys... I drove the car up the hill three times yesterday. My plan was to disconnect the O2 sensor after the first run. .....but it drove up PERFECTLY three times. So if I had disconnected the O2 sensor it would have proved nothing (at least yesterday anyway...) Curre...

Re: Weird power loss at high speed...(troubleshooting)

I haven't gone up the hill for a few days....but I will try it with the 02 sensor out as soon as I do.

Does anyone know what the typical life span of the fuel injectors would be...? I always thought they were pretty trouble-free for the life of the car....?

Re: Weird power loss at high speed...(troubleshooting)

....and the other thing I thought might be giving trouble is the knock sensor...? Although I don't know much about the how / why / when with the knock sensor? What is it's relationship with the ECU? Is it only called upon at certain times?....or is it "listening" constantly and if so, what...

Re: Weird power loss at high speed...(troubleshooting)

Thanks muchly for your replies guys.... I failed to mention in my OP that I changed the fuel filter last w'end when I fitted the new fuel pump. The filter actually wasn't particularly old....I just wanted to eliminate it from the process. I would like to get a read on the fuel pressure as rough diam...

Weird power loss at high speed...(troubleshooting)

G'Day, I have a strange problem with my '93 Liberty & I'm hoping someone might have some ideas about the cause...? (I'll admit I haven't searched the forums much because the problem is so strange and specific I doubt there will a post with the same scenario / problem...) The car is an AWD '93 Li...

Re: 4EAT TCU part number search

was the gear selector in the "1st gear" position? If not, try it in 1st gear and retest. Actually no, I only tested with the shifter at 'D'. Ahhh....I remember reading something about preset duty cycle levels for each gear. I think 1st & reverse always receive maximum "AWD" ...

Re: 4EAT TCU part number search

OK, the replacement TCU is now in the car. (whoever decided the location for the ECU & TCU was a good idea is a sadistic maniac. What's wrong with the front kick-panels?). I've only driven about half a gas tank but so far, so good. No TB. And for the first time in almost a year, the POWER light...

Re: 4EAT TCU part number search

Hey thanks a lot for the file, Leg777. It looks to me like, ROUGHLY speaking, 'AA' series was '90-'91, 'AB' series was roughly '91-'92...and 'AC' was '93-'94.... ...but as for the subtle differences between numbers....well, there's prolly 6 Japanese technicians/designers who know what they mean and...

Re: 4EAT TCU part number search

Thanks for your reply. Over the last 6-8months I have tried periods with the fuse in & periods with the fuse out. But either way it's the same - aggressive TB. The dash light for 'FWD" illuminates every time the fuse is in. (I believe this is relevant for some symptoms...?) ...but it doesn...

G'Day, First post from me...but a long time "lurker". Bloody good site this is. I believe in doing as much research as I can to avoid wasting anyone's time. I have an Australian delivered 1993 Legacy AWD wagon, EJ22E, with a slightly troublesome 4EAT. My car is the updated "series 2&...
