FSM manuals here i come!

thanks!

ive cleaned the TB twice and still the same result. When i push my clutch in coming to a stop the rpm's shoot up to 1500-2000 for 3 to 4 secs. Thats not normal. its crazy cause no SES light. everytime though it comes back down to perfect idle and at times it doesnt do it at all.

ive cleaned the TB twice and still the same result.

idle goes up to 1500-2000 when coming to stop and stays 6-7secs before returning to normal 750. And also noticing my throttle sticks at times. No SES light. please help!!

Thanks. I will try it

If thats the case with 3.3 not being able to relearn it. How do you go about it with the 3.3? Just go by what the FSM say's??

I will def try what the FSM says. Ive heard that the idle relearn doesn't work on all r50 pathfinders. Do you know if thats true?

What is the fsm procedures?

I was afraid of that. Ive got a Haynes service manual and in the troubleshooting section it say. "Engine lopes while idling or idles erratically." This is what it says in the manual. https://www.pinterest.com/pin/474426141977788853/ It says to check PCV valve it might be plugged up. I put a new one in and it made the idle worse. It idles at 1200 or more, up and down all around and never settles down to factory idle @ 700-750 rpm's. Checked for vacuum leaks also. No SES light so I cant run the codes. I tried to post a picture of the trouble shooting section from the service manual but I don't think I uploaded it right, I will check the MAF.

Ok wrong again. Didn't fix. Back at trying to find the problem. I'm stump.No ses light so no codes to check. Ive tried the spraying carb cleaner to find a vacuum leak and nothing. Maybe a relearn or something? I have a 98 and dont know if i can do that on mine. Replaced valve cover gaskets 3000 miles ago to fix both leaky sides. When I put it back together and ran it for 3 weeks with a check engine light and low idle, sometimes wanted to die on start up after sitting all night and not realizing i didnt hook the electrical connector up to the IAC valve for that period so I had to tear it back down again and hook the IAC up. Ran perfect except now this idle issue of all of a sudden at red lights my idle just jumps up from normal 750 to 15-1600 and may or may not come back down to normal for a few seconds or when it wants too. No SES Light!

Ended up being vacuum hose on bottom of EGR backpressure transducer valve. Hose was loose.

At times it runs perfect. Other times it does this. When coming to a stop I push the clutch in and the rpms shoot up to 15 to 1600 and will stay or at times it comes back down to the normal 750. I can also be sitting at a red light idle will be normal then all of a sudden the rpms shoot up to 1500 or so and it might stay there or it might come back down. I'm affraid it might be my IAC valve sticking or something. Is this possible? Please help!!!!!!
