Honda Civic X Jerks at low speed

bazil4 (Bazil Chaudhry) 2021-07-11 19:31:35 +0500 #1

Car: Honda Civic X 2017
Mileage: 57,000 km

Issue: At low speeds, especially when accelerating from traffic stops, the car jerks before picking up speed. The jerk is strong. Only happens when accelerating after stopping or significant reducing speed.

Can any pak wheeler help diagnose this issue:

Spark Plugs
Fuel Pump
Transmission

Did you change CVT oil at 40k?

bazil4 (Bazil Chaudhry) 2021-07-11 20:45:06 +0500 #3

Yes at 45k

Interestingly only happens on D gear, works fine on S and L

Happens with me as well, have gotten used to it now although I've yet to change CVT oil 45k km driven.

Better get it checked from 3S.

The 3S dealership is saying the catalytic converter requires cleaning. But why does the car drive fine at S gear beats me - shouldn’t the catalytic converter issue impact all gears

Cat should require cleaning at 57k km due to Pakistan's below average fuel quality which is now slowly improving.

Before getting your cat-con cleaned, I'd recommend you try to factory reset the ecu on your own and see if it helps.

Update- Tried using octane booster in fuel and the jerk is getting better. For the past few days no jerk while driving.

A friend thinks that this is actually “missing” and I should get fuel filter and fuel pump checked. He says since in S gear the car pumps/uses more fuel than in D. The jerk/missing in D is due to it not getting enough fuel at low gear probably due to the fuel filter and fuel pump.

Weirdly I got the fuel filter changed at 45k as well and also the fuel pump was changed by Honda in February ( in warranty). They identified the fuel pump issue themselves.

Not sure what to make of any of the above but if octane booster is helping - I’ll keep using it.

I wouldn't recommend you using booster..get fuel from company operated fuel pumps. PSO is offering Euro 5 fuel..try hi octane Euro 5.

I think fuel quality is main issue.

Get fuel from reputed pump and use hioctane with full tank.

It will be ok

bazil4 (Bazil Chaudhry) 2021-08-18 21:44:04 +0500 #13

Final Update: jerk has disappeared, using octane booster with regular fuel and at times hioctane fuel.

Most likely issue was with fuel pump or filter caused by bad fuel and has been resolved
