Car Forum / Nissan / Nissan Cars / September 2005Idle Speed Screw For 1995 PathFinder SE
Hi all, I'd like to adjust engine speed by turning the idle speed adjusting screw. But I can't find where it is. Can anyone tell me where it is located exactly. Any input is greatly appreciated. dannguyen1@verizon.net > Hi all, > I'd like to adjust engine speed by turning the idle speed adjusting screw. > But I can't find where it is.

Way to complicated to try and describe on an bulletin board. > > Hi all, > > I'd like to adjust engine speed by turning the idle speed adjusting screw.

If there is one, where is it close by? Thanks, > there is one , and it is hard to find. > [quoted text clipped - 9 lines] >> > >> There isn't one.

You have to check a whole of lot other stuff before starting to make adjustments to the idle. Need to check for fault codes. Ignition timing has to be checked at same time, some before setting idle others in a loop check/set idle, check/set timing, check/set idle, check/set timing...until you stop making adjustments. Some you have to disconnect the AAC valve when setting idle, others you disconnect the TPS, then set base idle 50rpm below normal idle. Can't tell you which to disconnect. When reconnected the ECU will control the ACC/IVAC to set correct running idle. You need the manual, $5 CD off E-bay, but some you can download for free, I have UK S13/S14 manuals (25Mb pdf), Pathy may be out there somewhere too you just have to look, peer 2 peer networks, bit torrent sites. Lots of base idle screws are set wrong to compensate for accumulation of dirt and coke in idle circuit, PCV, breather hoses, EGR, throttle plate etc. If the idle speed is wrong it means the ECU has lost control of this function and something is wrong - FIX IT. ok mr.know it all its on the back of the plenum. > You must be kidding!

Let him twiddle away! but OP's next post will be "My Pathy idles too high on startup" or "My Pathy stalls at junctions".
