Hi all. I guess this subject has been mentioned numerous times, but I think my scenario is a little different.
Nissan Navara 2006 (D40 4wd)
A year ago the car ran fine. The engine seemed to pulse in waves (just the sound of it), but that was all. I got some P0135 diag errors which I just kept resetting.
Then during Winter (Estonia, so it's cold) the car wouldn't keep running until the engine had warmed up for a couple of minutes and then it was fine. It just stalled on tickover and required the engine warm up switch to be on (keeping it at about 1400rpm). It was annoying, but I thought it was just the extreme cold.
However it started getting worse and it only ran well if the engine was fully up to temperature. Now it's Summer and hot outside, but not NOTHING will keep the engine running on tickover. When it's hot it will run for maybe 20 seconds on tickover and then just cut out.
Yesterday I changed the Post Cat Lanbda sensor to cure the P0135 errors to see if that helped. I've not driven it, but have left it running a while in the driveway, but the cutting out still exists.
Using Torque on my phone with a cheap dongle I can't see any O2 sensor readings, so not able to tell if the Lambda issue is fixed.
Also earlier this year I found lots of fuses were not in place (and never had been), so I just added correct fuses where there were blanks.
I cleaned the MAF sensor also.
Ideas?
