No worries, Soren.
Cars are such a headache lol.
It might pay to have another look at your MAP or MAF sensor?
The sensor itself can cut in and out during operation. So checking it with an ohmmeter with engine off and key in the “on” position may not necessarily uncover a malfunction. You can try to back probe the connection, try unplugging it and starting the car and see how it behaves afterward OR if you can afford to maybe replace the part.
The car should go into limp mode if you unplug something.

Though the fact that it improves the performance of the car is curious…and might be worth investigating further.No worries, Soren.

I was just thinking that it might pay to check the coolant temp sensor also.

Yes, well, it will be interesting to see the results of the pressure test.
Could be leaking injector/s? Again, just because it is clicking doesn’t mean that it is not faulty.
Does it seem like the car is flooded when you’re trying to start it?
Does the uneven idle smooth out if you feather the accelerator?
Does the exhaust smell petrolly?
Have you had a rise in petrol consumption?
Also, do an engine compression test, just to be sure.Yes, well, it will be interesting to see the results of the pressure test.

Also, do an engine compression test, just to be sure.Yea. Pretty much.
I will probably still poke around with a couple of things. I just really want to keep it running for a bit longer. I don’t want to spend a large sum of money on a new car just yet.
But really, there isn’t much point in going to the effort and spending the money to repair it i.e rings and such or a new engine the car is old and not in great condition anyway.Thank you very much everyone for your time and advice. I really do appreciate it.
Kylie 🙂

After speaking with my mechanic to retouch on the idea of leaking injectors to which he still didn’t think was “it” but said we could give that a go, he thought though that it is more of an air flow issue.
Aaaaaand then I told him of my compression test results… he thinks that this could be the issue. Said he will do a bit of research and let me know what he finds out.So, yay.

Hi Eric,
The injectors has been my suspicion from the start! The mechanics that I have been to have been of the belief that this could not be the issue.
I have done a power balance test as far as unplugging the injectors while the car is running. The engine seems to struggle at equal amounts with each on I pulled.
But yes, that is definitely something that I will look into further.The first time I did a compression test I did not have the throttle open, I did the test by myself and even still the numbers were not all that far off the second lot of readings.
With the second lot I had a friend help me and this time the throttle definitely was open each and every time.Hi Eric,

Thanks Nissan for thinking of us all by putting the sensor not only right at the back of the engine and wedged in under the starter motor, but also only really accessible from under the car and not leaving much of a gap at all to get your hand AND a tool in the space.
So far it STILL has a hard start/idles rough and has hunting RPMs (now more evident).
I am going to pull out the IACV tomorrow and give it a clean, see how that works out. I couldn’t undo the bolts holding in the IACV last time I tried. They are Philips head screws. SO I got an impact screwdriver and hoping that works to remove the IACV.*SIGH*
Could my compression be causing this problem? Or is it acceptable enough and all of this trouble is being caused by something else?
🙁
