today i cleaned the IAC valve and TB both of which are spotless, i even took the TB off to get it extra clean and to clean a little bit inside the manifold.

anyways. about 30 minutes ago i went to teh store (about a 10 minute drive). when i left the store, the car was completely warmed up and the idle was at 900 and fluctuating a little bit. by the time i got home the car was idling at 1100, then rised to 1250 and comtinued to fluctuate by probobly like 20-30 RPM. i have not yet tested the TPS to make sure it is functioning properly. other than a faulty TPS, what else could be causing my idle problems. i would just adjust the screw on the IAC valve to correct the idle, but the idle is never in the same place.


also, how do i reset the ECU? i attemted to reset teh ECU after i did all ym cleaning but im not sure if i did it right. i turned the screw all the way clockwise and held for a few seconds. then turned all the way counter-clockwise and held for a few seconds, then put the screw in the middle. was this right?

I am not sure if it reset ECU...but to clear codes it works as follow:

- gently turn the screw clockwise till it stops, wait for two seconds and return the screw in the initial position.
- wait for two more seconds and repeat it;

I believe it has more detailed description in stickies or in FAQ. Check it out to make sure you everything right.

the screw should be all the way counter clockwise after you are done resetting it...not in the middle!


also, have you checked the condition of your PCV Valve? that could be causing inconsistent idle.

well i did some more searching and found how to remove it. where can i buy a new valve? does any standard auto parts store have them or should i go to nissan?

also, when i remove the PCV valve, do i just taje a rag and clean the socket that it plugs into, or is there something mroe to cleaning this part of the system?
