Engine stalls/jerking when running

[b16sir_stock]

Have problem with the local Honda Jazz Manual 1.3 when running at RPM below 2K.
Note : Idling is normal (TB & IACV recently cleaned)

Pag andar mo from 1K to 2K rpm the car jerks/stalls ("kumakadyot").

Tried to have the coils inspected and they were replaced with surplus ones that are
working na. Also spark plugs where replaced na din.

Saan kaya nangagaling ang problem?
Any recommended shops QC/Manila that are experts in diagnosing this problem beside
casa?

check your high tension wires, distributor, fuel filter and fuel pump.

Isn't this engine equipped with COP (coil on plugs)?

yes and 2 were replaced already as mentioned.

yes and 2 were replaced already as mentioned.

All the coils were installed on the same day , ran the same number of miles. If one misfired, the rest will misfire in a few weeks if not days. You replace them as a set to save time and inconvenience

I think ok naman however in my case the problem persisted. I had the ECU checked by A.L Auto Parts in abad santos and found na may problem sa TPS.
error was 07-01 TP sensor voltage low. they adjusted it lang and un nawala. now smooth na yung takbo nya.

Kahit naka neutral?

haven't tried it in neutral what I know is that pag 1st gear umaabot siya ng above 3k rpm, pero pag nasa 4th gear na steady lang siya sa 2k rpm, as far as I know dpat lumalagpas un eh, though conconsider ko na automatic ung transmission ko, triptonic btw

Can you do 3krpm on 1st 2nd and 3rd gear? If the 4th gear is the only gear that is limited maybe there is a transmission issue. Last atf change? Manual transmission sabi mo earlier. Now its triptonic(tiptronic is the correct term).

oops my bad sir its automatic / tiptronic po pala sorry sir newbie lang, actually its a repossessed bought it from a lady since hindi daw nagagamit binenta na, I didn't know that last ATF change since 1 month plang sken, and pansin ko dn mejo, hnd mlakas ung throttle nya to be honest, pero nabasa ko kc since hnd ganon kalakas horsepower niya,

Also, pag nag sslow down ako from the 3rd gear nilalagpasan niya ung 2nd gear, pag almost full stop then shift agad sa 1st gear. any idea po?

mga sir maya katanungan lang ako. meron ako problem sa Lancer GTI 1992 EFI engine 4g15

pansin ko pag idle siya ng lalaro ung ung idle nya. minsan nmn steady lang siya tapos may time na bumagbagsak ung idle nya tapos aangat ulit pero since nka muffler ako hndi swabe ung tunog nya sa muffler parang may misfire na tunog parang may maliit na naputok sa loob ng chamber pero okay nmn ang takbo ko. ska pag naibyahe ko na ng 4hours straight may time na biglang mamatay ung engine nya. tapos need ko mg wait ng 2-3 mins bago siya start ulit.

additional problem is umaamoy ung gas nya sa tambutso. and every start ng engine meron white smoke na nalabas na amoy gas.

hndi ako ng babawas ng oil and coolant. FYI

salamat sa sasagot
