Vibration + dropping RPM during initial acceleration when A/C is ON.

Check muna throttle body, baka it needs cleaning dahil marumi. Check muna air filter, baka it needs replacement na. And fuel filter too.

same solution solved the issue.. ignition coil is the culprit. nag back read ako nakita ko nag comment rin pala ako na palitan ignition coil to solve this issue. i did before pero my mistake was replacement part binili ko.. lasted for a year then eto bumalik nnmn. nag linis nko tb, iacv, replaced pcv valve and hose, checked alt, batt, checked compressor and fans, even adjusted tappets.. na resolved lang nung pinalitan ko lahat ng surplus ignition coils!
now my car runs fine kahit may AC, pero nung na trafik ako sa QC sa kainitan ng araw, ayun maramdaman ko yung jerk at pag stall ulit. issue na ng honda yung ignition coils na pumapalya.. time to buy bnew orig honda ignition coils.

It is better na brand new, kaysa surplus ignition coil.

may kamahalan lang bnew orig na honda ign coil.. last time i checked with honda nasa 4.6k isa...

A replacement will do, at least brand new. If you find the OEM from Casa much expensive. Surplus parts mostly here in our country are not surplus, they are used parts already.

check your compressor pulley, baka tumitigas na and nag strain sya sa makina.

napapalitan ba bearing ng compressor?

Same here. 2012 honda jazz 1.3 MT.. pgstuck ako sa traffic tapos nirev ko yung engine. after umakayat ung RPM Babagsak sia sa round 400RPM at manginginig bago bumalik sa around 600-700RPM pg naka idle. normal ba un? Kung no rev. 600-700RPM then pgmagoon un fan nasa 800RPM wlaang nginig. Pgnagrevrev lang at bumagsak na sa baba un needle.

reason why nag jerk car kasi mababa ang rpm. dapat nsa 700 to 900 ata pag idle.. tapos sasabayan pa ng aircon.. lalo mas kailangan mas mataas na rpm. ignition coils may not always be the culprit.. pero possible kasi pag kinapos ng bato ng kuryente from coils to plugs ayun babagsak nga rpm.. pwede rin yung iacv madumi na.. need linisin. kasi alam ko nakaka apekto rin yun kapag idle ang jazz natin. better have your iacv checked and cleaned.. pag wala parin consider changing the spark plugs, pag wala parin check mo pcv valve and hose baka may leak, pag wala parin be ready to buy a bnew set of ignition coils. based from my experience ito ha.. everytime nangyayari sakin ito, ignition coils palagi ang nakaka solve ng issue. another way to check kung coils nga eh kapag nararamdaman mo na parang "sinisinok" yung makina mo.. kasi kinakapos ng kuryente.. malamang ignition coils yun. goodluck sir

I've been experiencing it too for the last 10 years on our Honda City SX8. Sa ngayon, may sapantaha na ako ano ang dahilan kung bakit ganyan din katulad sa nae-encounter mo.
