Reshma Posted June 20, 2011 Author Share Posted June 20, 2011 Even though she is warmed up she is supposed to rev high like that? she runs at almost 1500 when in drive sometimes. I think something is wrong. Link to comment Share on other sites More sharing options...
LostNcrRanger Posted June 20, 2011 Share Posted June 20, 2011 Looks pretty normal. the engine speeds up because it's not under load. Link to comment Share on other sites More sharing options...
Reshma Posted June 20, 2011 Author Share Posted June 20, 2011 Thats really normal? but what about in park. Shouldnt it be lower instead of way up where it was? Link to comment Share on other sites More sharing options...
LostNcrRanger Posted June 20, 2011 Share Posted June 20, 2011 Nope, most cars do it. if it worries you that much, turn it off, then put it in park. Link to comment Share on other sites More sharing options...
Reshma Posted June 20, 2011 Author Share Posted June 20, 2011 Interesting. IDK it just seemed really weird that it was idling so high. Even in drive when im at a light it will jump up to 1000-1500 rpms. If you say its normal then i geuss its normal. My dad says its not tho. im not quite sure.

Simon Posted June 20, 2011 Share Posted June 20, 2011 1000-1500 is not normal at idle. It should be 750 +- 50 rpms at any time, in drive, reverse, or park. Have you run the codes to see if anything comes up? Link to comment Share on other sites More sharing options...
Reshma Posted June 20, 2011 Author Share Posted June 20, 2011 No..I guess I should run the codes..if only I knew how. LOL. I'm Mega noon help me out here buddy Link to comment Share on other sites More sharing options...

silverton Posted June 20, 2011 Share Posted June 20, 2011 I'm going to guess you have a minor vacuum leak somewhere. just enough to bring the idle up, and not affect the drivability. Is the motor itself revving up? or is just the needle moving? I couldn't tell as there was a lot of background noise. I just ask because round dashes are known to have cluster issues, and you mentioned your fuel gauge does not function properly. Link to comment Share on other sites More sharing options...
BoneZ Posted June 20, 2011 Share Posted June 20, 2011 (edited) No..I guess I should run the codes..if only I knew how. LOL. I'm Mega noon help me out here buddy Try reading the stickys in how 2 read all them not just this 1 from sticky in garadge section I have seen this problem when I split the air tube between the throttle and MAF sensor. Look for cracks, they happen allot on bottom side of TB end where it is hard 2 see it. Edited June 20, 2011 by BoneZ Link to comment Share on other sites More sharing options...
WarehouseRat Posted June 20, 2011 Share Posted June 20, 2011 if your dad isnt a tranny specialist or a certified mechanic chances are he is dead wrong,its normal, if there is not check engine light there will be no codes, vacuum maybe, but it looks 100% normal it does idle lower when its out of gear at the correct rpm level, now if it idles to low in gear you would have a lock-up issue with the torque converter you wanna check for a vacuum leak then do a smoke test Link to comment Share on other sites More sharing options...
nismothunder Posted June 20, 2011 Share Posted June 20, 2011 Cold start in park should be around 1200, Now, what I think it could be, and is easy too check is the fuel pressure regulator hose on the rear of the intake. Link to comment Share on other sites More sharing options...

Mine stays at the 750~ even when in gear. I bet he has a vacuum leak. Check the on the fuel pressure regulator its on the back of the intake manifold and likes to fall off.

Towncivilian Posted June 20, 2011 Share Posted June 20, 2011 Throw some Chevron Techron fuel system cleaner or Gumout w/ Regane in your tank ($5-6 at Wal-Mart), that might help your fuel gauge - there might be some sediment or sulfur build up on the fuel level sending unit (or whatever the ball thing that floats in the tank is called).

Reshma Posted June 20, 2011 Author Share Posted June 20, 2011 http://www.nissanpathfinders.net/forum/index.php?showtopic=21 Looks like the pictures are dead though. Thanks. Gunna spend some time reading it soon. I'm going to guess you have a minor vacuum leak somewhere. just enough to bring the idle up, and not affect the drivability. Is the motor itself revving up? or is just the needle moving? I couldn't tell as there was a lot of background noise. I just ask because round dashes are known to have cluster issues, and you mentioned your fuel gauge does not function properly. Motor is revving too. Gas is the only problem in the dash currently.

Look for cracks, they happen allot on bottom side of TB end where it is hard 2 see it. Thanks for the info. Will be reading the link soon. if your dad isnt a tranny specialist or a certified mechanic chances are he is dead wrong,its normal, if there is not check engine light there will be no codes, vacuum maybe, but it looks 100% normal it does idle lower when its out of gear at the correct rpm level, now if it idles to low in gear you would have a lock-up issue with the torque converter you wanna check for a vacuum leak then do a smoke test We have had 2 pathys b4 mine. a 88 and a 92. He also rebuilt the engine in his ford. He also loves to mess around with engines and stuff. He is not a certified mechanic and im pretty sure not a tranny specialist but he knows his stuff. Cold start in park should be around 1200, Now, what I think it could be, and is easy too check is the fuel pressure regulator hose on the rear of the intake. Huh? picture location? What simon said, it's not normal. Mine stays at the 750~ even when in gear. I bet he has a vacuum leak. Check the on the fuel pressure regulator its on the back of the intake manifold and likes to fall off. fuel pressure regulator you say. Back of intake manifold you say. Can you explain the location of such a thing as if i had the IQ of Kyle. Throw some Chevron Techron fuel system cleaner or Gumout w/ Regane in your tank ($5-6 at Wal-Mart), that might help your fuel gauge - there might be some sediment or sulfur build up on the fuel level sending unit (or whatever the ball thing that floats in the tank is called). Good idea. I will get right on it...as soon as I get some money. LOL Link to comment Share on other sites More sharing options...

When you open the hood, look behind the top of the engine (at the firewall) you will see a little 6" hose, make sure it is hooked in and not cracked or missing.

adamzan Posted June 20, 2011 Share Posted June 20, 2011 Dude even mechanics are wrong sometimes. A 30 year certified mechanic didn't believe me that wd21 cv axles don't spin unless in 4wd with the stock hubs. He was surprised when I showed him. The truck isn't supposed to idle at 1300 rpm.
