Re: low idle on the pathfinder.
Check your air filter, intake tubing, ave clean the MAF sensor. They could all cause low/erratic idle.

Re: low idle on the pathfinder.
the haynes manual does not discuss cleaning it , only test it and replace it, I do not have a volt meter, on youtube there are some various ways to clean ie: a shot of some type of electronics cleaner.
-how much to buy a new MAF? can I buy just the sensor or is sold as a complete assembly?
- I run a K&N air filter I just cleaned it yesterday per the manufactures guidlines, and now I am running around 700 RPM at idle, what is the factory set idle?
-even with the air box open, the idle is still at 700 RPM

Re: low idle on the pathfinder.
the factory setting for the xterra is 750, don't remember the pathfinder off the top of my head
it is possible that over-oiling the k&n filter could have resulted in the mass airflow getting some oil on it.
there is a specific cleaner for mass airflows, don't use anything but this cleaner. A replacement sensor is in the 500-600 range.

There's a specific cleaner for the MAF? I've been using electrical contact cleaner for years with no issues. But if you say there's a specific cleaner put the name of it and where I get it.

Re: low idle on the pathfinder.
I've always used rubbing alcohol to clean the MAF with a Q-Tip. Be VERY gentle with the filaments inside the casing, they're quite fragile.

I think the rule is that some cleaners leave a lubricant residue, and some don't. Maf cleaner does not, as rubbing alcohol wouldn't either. I would read the electrical contact cleaner bottle and see what it says about residue.
The cans i have always gotten are labelled specifically "mass airflow sensor cleaner" that i get from napa.

Re: low idle on the pathfinder.
I am some what nervous now to clean the MAF. It seems very simple, I have already taken the MAF off to give it a visual inspection, but can I fuc.k it up by cleaning it with the proper MAF cleaner noted above.
If I do, this little fix will cost me $600.00
What would be an estimate just to get the dealer to do a quick spray clean?

Re: low idle on the pathfinder.
I got some MAF cleaner from Parts Source once and just sprayed the hell out of it. Let it dry (somewhere it won't get dirty) before re-installing.

Follow the instructions on the can and you'll be fine. Just handle it carefully, use safety glasses/gloves.

Re: low idle on the pathfinder.
i used this on my truck and my parent's vq35. You need a special tool to loosen the bolts that hold the sensor in the intake, but not for the vg33. The CEL was on the vq35 and it got rid of it. I also cleaned mine since I've never done so since buying it.

fwiw, my parents also had a KN filter on their r50 and I convinced them to ditch it and go with a regular paper filter instead. They don't wheel.

Re: low idle on the pathfinder.
I know all the mechanics I worked with called oil coated/soaked air filters MAF meter eaters! Yes they help a bit with mud and water protection, but cause more damage than good for every day driving. A lot of Nissan's that came in the door with erratic idle or codes for the MAF had or use to have the K&N type oil filters. I believe that OEM Nissan air filters come oil impregnated, so why not go that way?
I have also done the cleaning the way simon did except with out touching the sensor with a Q-tip. I just kept pouring it on a few times and it helped. I would also try a TBS and reprograming of the idle to help as well. Your throttle body could be gummed up as well and the truck is losing reference on fully open/shut.

Sounds to me like a little bit of dirt somewhere. Perhaps in the throttle body. Nice when it sorts itself out.
