Try resetting the idle again, disconnecting the TPS... but if it happens with the AC, then it might be something with your IACV.

sir anu po yun iacv? magkano po yan? maraming salamat po sir, i hope umayos na yung auto, nakakaistorbo pag nakatigil sa trapik.

hope ko mura lang

anyway gusto ko lang po magadd dun po dun sa pag tune nakita ko kasi sa fsm (factory service manual)(pwede niyo search sa google nissan fsm pero hindi ko sure kung saan makakdownload) na before idisconnect yung tps i rev muna at 2,000rpm around 2 mins, tapos dun tatanggalin yung tps at tsaka dun mu iaadjust:P

Sir Kulotz,

IACV means po ay Idle Air Control Valve. medyo mahal po yan, natanong kuna sa nisway its php7,945. From FSM its says po na after you set the idle, ikabit uli yung TPS connector then rev 2x to 2000 to 3000 rpm. Then idle should come 650 to 750rpm. Tapos turn the A/C on it should come up to around 900-1000rpm. Pag pumalo po sa 900-1000rpm after turning the A/C on, that means your IACV is working well. Sa IACV rin po nakakabit dun sa dulo nya yung Idle Screw. Just to let you know sir, nangyari din po sa aking oto yang problem nyo. So what I did ay nilinisan ko lang yung IACV-AAC valve dahil ang daming carbon deposit. After then ay stable na ang idle ko. To remove the IACV-AAC valve is first you have to remove the Throttle Body kasi mahirap kapain to remove yung dalawang bolts na nasa ilalim ng IACV-AAC valve. Actually it has four bolts. Dalawa sa itaas at 2 sa ibaba facing the engine. If you can take the four bolts out using a special philip screw driver that would be a great to save time and work.
Try cleaning your IACV-AAC valve.

If it doesn't fix your problem then try regrounding your MAF sensor

Good Luck!

hello sirs update lang.

inadjust ko na yung idling gamit yung sa fsm at maganda na yung tono, ginamit ko ng matagal at inidle ko ng matagal okei na siya

tapos inikot ko with a/c okei naman kahit nakaidle pero nung nagtagal about 5 mins bigla umangat rpm nung nag on yung compressor ng sobra tapos the bad part kahit nakapatay compressor ang taas parin, so antay parin ako about 10min. nagnormalize idling tapos after 15 min tumaas ulit sabay biglang bagsak patay makina, tapos inon ko ulit na naka patay aircon okei ulit tapos pagkaon ng aircon nginig agad patay ulit, ginawa ko pinatay inon ko sabay off agad tapos on ulit ayun di na namatay, tapos ikot ulit tapos idle nawala na yung topak nya

siguro nga yung iacv ba yun tsktsk, linisin ko nalang pag me time sori sa long post
