Ok,let me clarify myself… If i follow the procedure from 1 to H and using scanner tool to clear the code,,,do i need to proceed number 4 (disconnect the battery for 12 hrs) after? thanks again

Thanks for the quick response, can i erase the code by using obd2 scanner instead of disconnecting the battery and do i need to drive the 25 miles continuously without shutting the engine off for this procedure? Thx

[quote=”Boyet” post=155296]I have 2001 nissan altima auto,4 cyl ,85k and the idle is at 1400-1300 rpm during startup, it goes down to 1100-1200 rpm after warmup,,normally it should be in 800-750 rpm,, i cleaned the idle air control valve and adjust the idle screw and also i replaced PVC valve but no changes,,,any suggestion is greatly appreciated,thanks

Is there a idle learner procedure on this car to makes the rpm down to specification ? I heard its apply to 2002 and up model only

[Carlos]

So it has to be every 3 months regardless of the mileage? Im guessing including the oil filter too? Thanks
