ChrisFreeman Posted March 28, 2014 Share Posted March 28, 2014 I have a 92 pathfinder and I have concluded that the idle air control valve is either clogged or the motor is not working properly. Is there any way I can clean the valve without removing it. It is in a recessed part of the engine and It seems hard to remove. Thank you Link to comment Share on other sites More sharing options...

gv280z Posted July 21, 2014 Share Posted July 21, 2014 Let me guess, your truck dies occasionally when you come to a stop, or it idles roughly around 300 rpm and blows black smoke, right? When mine did this, I also narrowed it down to the iacv, which I was able to remedy by having a 3 step Gunk fuel system treatment performed at my local kwik kar oil and lube station. What I really believe dealt the crushing blow was the 20 minute iv vacuum line drip with the engine running, they also put a bottle in the tank and spray cleaned the throttle body. After that it was fixed and never came back again. Link to comment Share on other sites More sharing options...
Kafike Posted July 21, 2014 Share Posted July 21, 2014 I didn't bother cleaning it. I just removed it and bought new. It's actually not too bad. The hoses in the back are a pain though. Pricey part too. Link to comment Share on other sites More sharing options...
