aj503 Posted March 17, 2014 Share Posted March 17, 2014 Just curious about what the cold idle speed is supposed to be, i.e. right after startup until the fast idle cam is in position? Mine is steady at 2000 or so then dropping to about 900, which is close enough to the 800 that is should be for me when warm. Link to comment Share on other sites More sharing options...
intheshadows Posted March 17, 2014 Share Posted March 17, 2014 I was just going to post this as well, as my idle from a cold start is about 1750, which will go down to 1200 while in park after shes warmed up. I thought this was high My truck takes forever to warm up though, even when its 80F outside. You guys in the cold must have one hell of a time getting your pathys warmed in the winter. The second I throw it into drive, it will sit around 900-1100, cold or hot. Behavior is very predictable and she drives like a dream. Link to comment Share on other sites More sharing options...
aj503 Posted March 17, 2014 Author Share Posted March 17, 2014 It actually warms up quickly regardless of weather for me just a few minutes at idle or driving. Idle specs are different manual and autos as well. Link to comment Share on other sites More sharing options...

A little bit on the high side if it is that way consistantly regardless of temperature outside. You might want to check your timing and see if it is correct as well as the vacuum hoses for any leaks or holes..

aj503 Posted March 20, 2014 Author Share Posted March 20, 2014 Is the cold idle part about where it should be? Link to comment Share on other sites More sharing options...
Terranovation Posted March 21, 2014 Share Posted March 21, 2014 Mine sits on 750 when I start up, when warm it's at 800. Also remember when in P or N the revs should go up a little bit. It should be noticable. Link to comment Share on other sites More sharing options...

I just got done fiddling with the timing, but I didnt play with the idle adjust screws. I inspected my vacuum lines and they appear fine, but theyre old and crumbly looking so I dont doubt there is a leak somewhere. Havent gotten around to that yet. My timing is sitting at ~14 BTDC. Seems to run slightly smoother there than 12 or 15, but could just be in my head. Link to comment Share on other sites More sharing options...

SpecialWarr Posted March 26, 2014 Share Posted March 26, 2014 Question: why do we adjust the timing in neutral instead of in park? Are there other things running in neutral? sent from under Ernest the Pathfinder Link to comment Share on other sites More sharing options...
Alkorahil Posted March 26, 2014 Share Posted March 26, 2014 So that there is no load on the motor. Link to comment Share on other sites More sharing options...
