gq 4.2 tbe starting but not continuing to run???

maf or air flow sensor, is the sensor located on the outlet of the airbox. a stuffed o2 sensor wont stop the vehicle running, will cause it to use more fuel but thats about it, the o2 sensor only comes into play while cruising.

We have swapped the sensor itself but not the whole unit but will do. I have been a bit slack on working on patrol as it has been 46 - 48 degrees in the shed when I get home from work.

thanks to all who had input to our problem. Today I went to swap air flow sensor from my patrol and noticed that the one on my sons patrol was back to front. Turned it around and it started and runs fine(with computer from my patrol as his has died). The sons patrol has a air cleaner off a diesel patrol and air flow sensor is mounted on inlet hose. He had pulled it apart sealed it up after reading an article about leaky air intakes. We now need a computer to finish off his patrol.

thanks again for all your input as it helps to have other peoples ideas.
now I have nearly enough posts to download the manual.

You don't need a manual, you have nissanpatrol.com.au

Good outcome mate.
But yea stick about. The members here are full of a lot more Info (and other stuff) than you'll find in any manual.

But enjoy the running car..
