I am new to this site and my new Pathfinder for that matter. Anyways, I have a few questions about my engine. The motor has 225,000 km's on it.
1) My engine hunts for an idle while it's warming up: It surges to 2000+ rpm and the hiney drops out of it down to 1000 or so. What could be cuasing this? The throttle positioning sensor?
2) Also, when I am driving it cold and I rev it up to 3000+ before a gear change, the rpms stay up at 3000+ for a second or two even though my peddle is let off. TPS also? Sticking throttle bodt linkeage?
3) Once it warms up, it kinda feels like it is missing on one cylinder when idleing. Once I give it a little gas it clears up. WTF? Do I have a toasted plug or something?
4) Also one of my motor mounts (drivers side) is missing it nut. It was popped out but I put it back into the hole. Does anyone know what size nut it is. It seems to have to be a pretty thin nut to fit it in there.
Cheers
and thanks for listening
