assalam o alikum
can we check without opening the catalyst to see whether the catalytic converter is installed or not? and what is the location of catalytic converter in liana.

You might have to show him a video or photo of how it is done, but I think he might be able to do it.

Salam everyone.

Meri liana 94k odometer original engine mai koi error code nahi ha scanner se check kia ha lekin throttle response consistent nahi ha.

New Ignition Coils
Throttle body cleaning,
catalytic washed,
spark plugs cleaned,
engine oil changed Total Quartz API SN 10w40,
air filter changed,
oil filter changed.

lekin kabhi gas pedal pe boot Achi pick ha

kabhi mar jati ha kabhi Achi pick ha

Note: Thermostate installed

Sounds like an electrical problem. Check wiring.

@saboor73 @Xulfiqar @Proverbial_Slang @capsat guys your comments?

Xulfiqar (Xulfiqar) 2023-10-06 18:51:14 +0500 #16854

Check fuel pressure when engine accelerates under load and check tappet clearance

saadsaeed.ku (Saad Saeed) 2023-10-06 18:54:18 +0500 #16855

sure @Xulfiqar, could you please recommend any good mechanic for my liana. Anywhere in Karachi please? It would be helpful for me. I have recently bought this

saadsaeed.ku (Saad Saeed) 2023-10-06 20:54:37 +0500 #16856

guys any good mechanic for liana ?

That can work properly and diagnose

dani_kk (Dmotorsports) 2023-10-20 03:05:34 +0500 #16857

For now check the fuel pump pressure by connecting fuel pressure tester don't rely on mechanics keeping a hand in front of fuel line saying "sir pressure buht taiz hai ungli nai rakhne deraha*

The readings should be 40-45 psi as soon as you turn on the ignition and start the car. Then later on remove fpr vaccum feed pipe the pressure will rise Further confirming fuel pressure is good. Keep the gauge connected for atleast 30-35mins to see if the pressure drops or not. Looks like you are getting inconsistent fuel pressure due to clogged fuel filter located in fuel assy. For this you have to remove fuel tank.

Also I have noticed one more thing. When AC is turned off, my liana take a very little load and the jerking problem also minimized unto 70%.

AC on it cause more jerk and slow pick up

Proverbial_Slang (Proverbial_Slang) 2023-10-24 13:45:03 +0500 #16859

Replace spark plugs, as it is cheaper. If not solved, carefully check ignition coils and apply dielectric grease on the boots.

@Proverbial_Slang issue resolved by changing the spark plugs to BKE6EYA-11.Another problem arises, car pick-up slows down also, fuel consumption dropped from 11 to 9.

Please note it had BKR6E**GP** NGK G-Power plugs installed when it was giving jerks issue but the mileage and pick-up was far better that it has now...

BKE6EYA-11 installed but the manual says BKE6E-11. Does it really has any difference at all also what could be the reason for the low mileage and pick-up, sometimes in rush, I push the gas paddle more than 50% but there is no response of throttle??

Thermostate installed
Oil using 10w-40 API SN.

Radiator filled with Coolant

Please guide me now... @Xulfiqar @capsat @dani_kk

Proverbial_Slang (Proverbial_Slang) 2023-11-06 10:37:13 +0500 #16861

The only difference I can spot is the last letter in the spark plug code, which is "A". It means you installed a spark plug which does not have a gasket.

I don't think it will seal properly, and will result in loss of compressions and missing.

saadsaeed.ku (Saad Saeed) 2023-11-06 13:10:19 +0500 #16862

Should I go for Ik-20 Denso plugs?

Because BKR6EGP G power are the new ones installed initially but giving jerks issue, although pick and fuel average was good on those, which were replaced by BKR6EYA-11 later on which show low pick-up and bad fuel avg problems.

What do you suggest to me? Is it really a spark issue or should I install BKR6EGP back into it and look for something else.

Please suggest me I'm really stuck in this situation.

G-Power are working fine in my car. The issue could be some thing else. Do check the ignition coils and their connections. Scan the car as well. It could be an O2 sensor issue or something else.

saadsaeed.ku (Saad Saeed) 2023-11-06 18:09:30 +0500 #16864

Are you using BKE6EGP in Liana 1.3 manual @Proverbial_Slang?
