Yeah, ill have to wait til the weekend as thats the only time ill see it in daylight!

Well thats correct then. Do you think the vac would cause such an issue? Do you think the high idle and the dodgy running could be related?

Yeah, my FPR is plumbed as yours is shown. If ive made an obvious mistake (though i dont think my problem is fuelling as i mentioned), the one on the right in your picture is the return, the other in the 'fuel in' right? Errrm yeah ive checked for vac leaks, ill show you what ive done. Would a...

Right, so i replaced the lambda sensor to no avail, still exactly the same problem. It starts and runs fine (idle is a little high) and i can pull away and am not limited by speed. Where ithas problem is under increased load so when i try and push it harder it just stops responding and starts...

Ok thats cool, with any luck this will be the fix i need. That means my spending money on car budget free up some beer money for bushwhacker budget lol

I dunno, i just want the right thing, eliminating chances that it will be replaced but still be wrong. Would a faulty lambda put it in safe mode or am i still going to have that problem?

hmm thjink ill go denso, should have thge right plug on and stuff.

Or even a genuine denso like this: http://www.ebay.co.uk/itm/Lambda-O2-Oxygen-Sensor-LEXUS-LS-400-4-10-1994-to-07-19-/270571472371?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3eff5105f3&_uhb=1

ahhh HAH!! so its the lambda sensor, did a couple of checks today and im getting continuity across the 2 black wires which im not getting on the other lambda which seems to be bad! Though if someone could confirm that would be excellent. Im pretty sure this would send my fuelling up the spout...

Ill go get the ecu part number in a bit. What is it about the wiring that means the CEL wont come on? Id have thought the slightest thing wrong would mean it should be on. Does anyone have a guide they used? As i said my engine runs and drives ok. Just overfuels badly and seems to be in some...

I took it off as i dont think its necessary because you can normally run the fault test with a lamp on the ecu. I built the loom on the engine so i dont think theres anything wrong with it, nothing that goes from the engine to the ecu has been tampered with. the diagnostics port is just loads of...

Havent got e obd1 port anymore, im manually putting TE1 just to earth from the back of the ECU. Ive got a 12v perm supply (from ignitors) to a 12v bulb to the W wire (unless this is in a different location after i changed ecu before). I put the 12v to earth to check and it illuminates. But i...

Ok, more questions (this is a battle of attrition), im still struggling to get the management light on. Is there some kind of trick on toyota ecus as i had the same problem with a 1JZ conversion before. Do i need to earth the ECU body? Does the management light come on regardless of fault when...

Ok, a little update. I spliced a chassis earth into the E2 earth wire I didnt want to just cut it. On the wiring diagram the EO1 and EO2 both just terminate direct to earth. I checked continuity and it is earthed but is it possible to just cut the wire and have it go direct from the ECU to the...

ok, cheers for the heads up, ill chop them and earth them and see what happens.

Ok, do i need to earth both heads? Ive earther the block and one head and im getting continuity from the other side to the chassis so should be ok. Ill take a closer look at the earths from the ecu and make sure they go straight to the chassis. The worry i have is that i cant cut them and run...

hmmm, that doesnt clear that up then. Its pointing to lambda at the moment as its overfuelling like nobodies business. Its costing me about £1/mile at the moment!! I will see where the E02 disappears off to though, am i right assuming i should trim it and put it to my chassis earth then...

Hi guys, i know i keep asking alot so sorry for the spam. Im hoping someone could shed a little light on something ive come across during my searchings on the internet and it says this: ... (Core Wire:A must connect) -E2 Common Sensor Earth, NOT the same as E1,this is the sensor earth common...

Right, so ive got the car driving again which is good. Back to some old problems though. The idle is now just quite high (1300rpm), rather than the hunting i was experiencing before (when warm). But as mentioned before my ISCV is showing out of range resistance values. I will endeavour to do a...

So i turned up another document outlining the resistance values, it transpires i am within spec for the TPS. Thats annoying because now i dont know what the problem is again.
