Elantra Kadyot problem

[Jecoism]

Hi guys,

Need the help of the experts. Our Hyundai Elantra jerks / kumakadyot during acceleration starting at 30km/hr. We brought it to Hyundai Quezon Ave. but they weren't able to solve the problem. We tried gassing up higher octane gasoline and even changed to Shell from Petron. A street-side talyer suggested changing the spark plugs and it worked... FOR A WHILE until we experienced it again yesterday. Any ideas what might cause this problem? TIA.

what year model? 1.6 or 1.8? if 1.6, m/t or a/t?

Hindi ba shift shock yun....

2012 Elantra 1.6 A/T. We cleaned the stock spark plugs and installed it again. Nawala ulit yung kadyot. Pero not sure if this is a long term solution. Hoping for suggestions or at least refer a shop that specializes on Hyundai cars (other than HARI dealers).

Under warranty pa yan ah. What did they do after they failed to solve your problem?

Wala bro. They just left us hanging. Hindi daw madetect sa computer eh, so we're left with no other choice but to solve it on our own.

Bulok talaga after sales service ng HARI, try to find a talyer that could read the ECU para malaman kung totoong di madetect sa Computer.
They might be trying to skip out on the warranty. Good Luck!

Lalabas siguro sa computer nila ang error pag wala na sa warranty elantra mo.
Nag check engine light ba?
Ano fuel gamit mo?
May ginamit kabang oil additive?
Within level ba ang engine oil mo? Dba sobra?

Try to clean your sensors first, baka air and fuel mixture combo lang issue mo.

Also yung air filter mo rin baka madumi na.

Diba dapat lumabas sa computer diagnostics kung may problema sa sensors or mixing problem?

[jaymd]

probably a fault sa ecu kaya may spark plug fouling ka

Yung mga nabasa ko sa ECP forums ay inhibitor switch problem naman pero yun, hindi talaga nag-start, kinakilangan ata a couple of starts para umandar.

kaya pala sir andun pa din yung problem ng elantra ko kahit na nagECU update sila, lalong nadagdagan pa yung problema dahil lumakas lumaklak ng gasolina pagkatapos ng update, ganyan din nangyayari sa elantra ko hirap mag start, kailangan pa ilang try bago mag start, tapos ang lakas ng amoy ng gasolina.

Bro, ano na nangyari after the ECU update at lalong sumama ang FC ng Elantra mo at pati yung hard starting? Nasolusyonan ba? Sa mga nabasa ko kasi yung inhibitor switch problem was claimed through warranty and it happened at mostly when mileage was 10-15T km.

Kakabili ko lang ng Elantra 1.6L A/t ko last May, sana di magkaproblema.

You should join the ECP forums (unless you already joined) and you can post your problem.

sorry sir sa late reply, medyo busy sa kabila, nawala yung hard starting nung umpisa, pero last week bumalik ulit, hirap ulit mag-start and lakas ng amoy ng gasolina, lumakas din laklak ng gasolina ko, less than 90km travel ko 3-4 bars ang nabawas sa gauge, pure highway lang. nung nagpa-fulltank ulit ako ang manual computation ko is 6.2+km/liter, pero sa trip computer 8.7km/liter. yung nagumpisa ang problem ng hard starting ng elantra 1.8 ko wala pa yata syang 5k kilometer, di ko sure pero check ko sa record mamaya.

[maimaicomp]

tama kayo sir 3ple4, almost 10k kilometer na din yung mileage ng elantra ko nung nag occur yung hard starting.

5-6 km/l din yung actual ng 1.8 elantra ko. Pero never kopang na experience yang hard starting.

sir pure highway lang yung 6.2km/l ko ngayon, nung hindi pa na ecu upgrade nakaka 11-13km/l pa ako noon, yung 6.2km/l ko dati pure city lang.

Ang lakas nga lumaklak for highway drive yung 6.2 km/l. Average city drive ko is 7-7.5 km/l by manual computation. I don't rely on the computer kasi feeling ko accurate pag manual computation. Kahit lumipat ako sa Unioil Euro4 gas, same pa din ang FC.

Boss, nakasama pa pala yung ECU upgrade sa FC. Shempre kamot ulo lang yung casa kung bakit nagkaganyan.

Teka nga pala, so besides your problems with HNE about the rack n pinion, nagka-problema ka din sa FC due to ECU upgrade and hard starting issues?

5-6 yung city driving ko, nasa 8-9 yung highway. Malakas nga kung 6.2 yung highway mo. Ano fuel na gamit mo? Experience ko nung gumamit ako ng high octane na blaze parang may butas gas tank ko sa lakas lumaklak ng gasolina.
