Gremlin_Offroad Posted October 19, 2014 Share Posted October 19, 2014 Mine has been doing that too I'd check your mass air flow sensor or check to make sure your egr valve isn't sucking in outside air Link to comment Share on other sites More sharing options...
gv280z Posted October 19, 2014 Share Posted October 19, 2014 Hey guys a LOT of us have had this here and has been covered extensively: http://www.nissanpathfinders.net/forum/topic/35159-engine-stalls-while-driving-help/ http://www.nissanpathfinders.net/forum/topic/38158-help-1994-pathfinder-stalling-issue/ My guess is Idle Air Control Valve and as I've told countless others, the trick that did it for me was the Gunk 2 stage fuel system treatment with 20 minute IV vacuum line drip at a local Kwik Kar oil and lube service. Has never come back to haunt me. You guys could have a loose MAF ground wire or check to see if you've got any codes thrown from the engine.
