Erratic idling when caught in traffic

[manley]

Mga Sir, seeking for your inputs once again... My car is 96 VTI stock PH16A engine

I am experiencing intermittent erratic idling when caught in traffic. Tumataas up to 2K rpm. As far as I have observed, it happens when AC is on. Pag pinatay ko kasi AC bumabalik sa normal. Pag wala masaydong traffic parang hindi lumalabas ang problem. Ano kaya cause neto?

Looking forward for your valuable inputs.

Thanks.

could be vacuum lines then. you may also want to have a mechanic check your TPS. It might be a bit off kaya erratic idling. Happened once with my 1995 Galant Vr V6.

yung dati sir parang suppressed ang takbo sa 2nd and 3rd gear pag bumitaw ako sa accelerator. Ngayon naman tumataas ang idling pag traffic with AC on.

Aside from IACV and TB cleaning, na-check ko na rin po ang TPS and ok naman ang reading. Check ko na rin vacuum hose. I'm thinking na baka sira na IACV ko like what hondacrv1889 said.
