Important! : fuel trim bank 1

18th November 2011, 15:35

Still got fuel trim bank 1 any advice got no sensor for the cat would this not help? Still cutting out when you stop and I have seen oil leaking out from the oil cap.

Sorry whats going on? Oil being blown from the oil cap suggests pressurisation of the crank case

Either excess oil in your engine a crack
ed/split breather hose or an internal engine fault would cause the oil spurting out.

+ try this for the fuel trim bank.

As the engine had lots of new parts thinner oil was put in might just need new oil cap what a fuck on might just get rid

going to dump the oil tomorrow and put some other oil in 10/40

fuel trim bank 1
is your front lambda sensor....

18th November 2011, 16:15

this is what i was told from OBD

MIL (Malfunction Indicator Lamp) Illumination
Start and stall
Poor fuel economy
Black smoke at tailpipe
Hesitation/misfire at idle or under load

Causes

Potential causes include a vacuum leak, unmetered air leaks Fuel saturated engine oil Leak in turbo air charge hoses (if equipped) Possibly bad O2 sensor (If Mercedes, may require adaptation with M-Benz compatible scan tool.) Oil contamination in MAF connector or O2 sensor connectors. Also check ignition coils, cam and crank sensors, and oil sensor for leakage contributing to oil intrusion in wiring harness. Defective MAF (Mass Air Flow) sensor (especially on Mercedez-Benz and other European autos. There are a lot of problems with aftermarket MAF sensors.) Defective fuel pressure regulator Leaking camshaft adjuster solenoids (Mercedes-Benz).

NOTE: for some Mercedes-Benz models there is a service recall for a crankcase vent hose located under the intake manifold. It should be checked for leaks/cracking and also operation of check valve in the hose. The check valve should flow only one way.

Front lambda sensor mate nearly 100% sure.

18th November 2011, 16:47

just had a look at the dip stick and its way over the max mark would this fuck the car up going to dump it tomorrow thats why oil is coming out the oil cap

its only done 67 miles

18th November 2011, 18:22

Yes your engine will leak oil if it`s overfilled.

19th November 2011, 11:16

From the pictures in your other thread, you have the wrong oil cap. One of these is what you want.

Sounds like you need a new pre-cat lambda sensor.

19th November 2011, 11:54

After spending the amount of money you`ve spent on the car I wouldn`t be dumping it.

Just sick of spending money on the car and its not any better

the clutch is getting worse

19th November 2011, 18:29

Get a used lambda sensor to get the car running properly,then when you`ve got the cash get a new one.As regards the clutch(if it was you)that did the engine swap then you should be able to whip the gearbox out & change the clutch yourself.Trust me if you`d seen the amount i`ve spent mechanics wise on my saxo you`d keel over lol.

The clutch is new I did not do the engine swap some 1 else did it, it gets stuck in reverse? Got another gear box of my VTR and that runs good. Going down on Monday to get a new lambda then I no it will work

did a bit more reading and it sounds like the front lambda sensor and Its going through the fuel to fast

19th November 2011, 18:46

You`ll soon know with the lambda sensor,because when you remove it,it will be sooty black in colour(if it`s overfuelling)

19th November 2011, 19:27

I will take it out tomorrow and have a look and give it good clean thanks for your help much appreciated

Do you run some form of quickshift? Might be worth adjusting it, if you can.

Yes I do have 1 going back to the standard 1 see if thats any better

24th November 2011, 17:19

Well I have done all the sensors, faulty water tempter but runs like shit cuts out all the time very black sooty spark plugs and smoke out exhaust should of put it in my self

any advice its going in next week so kev might find the prob

24th November 2011, 17:53

So you've replaced the pre-CAT lambda and coolant temp sensor and it still runs crap? Does it run any better if you disconnect the lambda?

A shot in the dark, but when was the fuel filter last replaced? Might be worth changing it.

24th November 2011, 17:59

Have you thought of getting the injectors ultrasonically cleaned?(a long shot)

if i unplug it its dont run good at all could it be post cat ? thats the only sensor not in

still saying fuel bank 1 even when i reset ecu i will have to have a look at the loom might be the problem

24th November 2011, 20:25

Ah right, so lambda is new and injectors have been cleaned.

I'd be tempted to try a new fuel filter personally.

EDIT: Forgot to say, the post-CAT sensor doesn't affect how the car runs in any way. It does store a fault code in the ECU though, but I can't remember which one.
