Try cleaning the air flow meter, and of course put a new air filter in it.

If you are running a reuseable filter, clean your air flow with some sort of contact or carb cleaner as the oil from the filters gets stuck on the airflow meters.

Hi,
I to have a NH 3ltr and my workshop manual has no instructions on how to replace O2 sensor or clean air flow meter so can someone explain how and what sort of cleaning agent is required to do the job

Thanks

THe 02 sensor in in the exhaust pipe located near the gear box it has a 4 wire connector to itand can be stubborn to get out TIP you dont need to but from mitsi cost is around $800 go to repco get for 150 or so can even get them on ebay ...these may require you to wire them up but are basic.
search is your friend I'm sure you will find help with it here

Cleaning the air flow is just a matter of taking the air box off (between air filter and motor) there is a small diode on the inside top use an old soft tooth brush with water to begin with maybe a bit of degreaser I dont think scrubbing the thing with harsh solvents is likely to do it any good

After replacing theox sensor in my NF I had about 3 L per 100 k better ecnomy. (didnot notice any differance in power)

I got my sensor off ebay (from a gut in Ringwood melb). It has to be 4 wire, plus I had to work out the colour code change.

Is you vehicle a manual or auto, if auto is it changing gears correctly?

An auto with 170ks on the clock.

Is the kick down cable adjusted correctly?

Due for a 170k service shortly so will get it checked out.

170k have the injectors ever been serviced?

Post by **Salty** » Sun May 18, 2008 11:52 pm

Not since I have owned it ! It had 80 odd k`s on it when I got it about 8 years ago. How do I go about it if required.

Take it to mec they will remove them and ultra sonic clean them.

DONT get talked into on car cleaning its cheaper and easier, but ud be better giving your money to a homless bum.

most vehicles could do with inj service every 100k, i got to get mine done soon
