Hi everyone I'm new to this forum but it looks like the place to be. I'm have a little trouble with my 2002 Ti Pathfinder Vg33e engine.

About a month ago I started stalling at the light but randomly ever now and then,

This is what I have done in order of this list .

 

Oil Change new filter and 15w40 oil . Weather is 25c to 35c in summer now

Air filter

Fuel filter

Change Bosch platinum plugs

Brand new leads

-

I've also taken it to three machanics and first one cleaned my air flow and next cleaned airflow and Map sensor. The next one blocked my Egr valve off with ball bearing in the air tube . And had it for a week then he said it came up with it saying a code about the distributor inside so I replaced with a second hand one and now I'm still stalling at random times !

I've had this engine for three years and it didn't seem wright from the start plus I've had my Pathfinder for 10 or more and it's my baby I try to keep it in good nick

please help a Pathfinder owner out !!!
