BobbyD Posted April 22, 2007 Share Posted April 22, 2007 Hi! About 2 months ago my Pathy(95' SE-V6)started having very erratic idling when stopped at a light or slowing down to make a turn. The idle would go from 1,000rpm to 400 and below and stall! I brought it to my local mechanic and he replaced the air mass sensor. It was OK for 2 months and now it is doing it again. The exhaust also stinks! He got the pathy in his shop took out the A.M.S.(air mass sensor)and sent it back to the auto parts store where he got it and said it was faulty. OK, I get the pathy back and it is good for a week and it starts doing it again. My mechanic said if I were in the area when it was acting up to bring it in and get him right away so he could actually see it and experience what was going on. Has anyone had this problem before with their pathfinders? Link to comment Share on other sites More sharing options...
Guest SuperSon Posted April 23, 2007 Share Posted April 23, 2007 Could be the plug for the sensor. Look at the connectors inside and if they look so spread apart just have your mechanic tighten them by using a small flathead screwdriver. This has always been overlooked. Start your truck and wiggle that connector,If the idle changes then you know that it just needs to be tightened Link to comment Share on other sites More sharing options...
88pathoffroad Posted April 23, 2007 Share Posted April 23, 2007 That's the mass airflow sensor, and check the wiring plug for bent pins or looseness. Link to comment Share on other sites More sharing options...
GrimGreg Posted April 23, 2007 Share Posted April 23, 2007 The exhaust also stinks! That is usually a bad cat. Maybe have the mechanic check it and the O2 sensor. Link to comment Share on other sites More sharing options...
Simon Posted April 23, 2007 Share Posted April 23, 2007 The wiring is common to fail on the MAF sensor. Mine does it sometimes, and when it's acting up, my exhaust smells as well. My idle is also erratic at that time. Typically, I just wiggle the connector, and the wiring for it, and the problem goes away. Link to comment Share on other sites More sharing options...
88pathoffroad Posted April 23, 2007 Share Posted April 23, 2007 Oh. Check your ECU error codes. There's a pinned How-To on that in the Garage under the How-To section. Link to comment Share on other sites More sharing options...
