Suzuki Liana No Power when engine is cold on petrol for 10 minutes

[pwuser156110487549]

Guys , This is my first post on this forum,I recently bought a Liana and have thoroughly tuned it,Throttle body Cleaned, New TP sensor Installed,New Spark Plugs Installed,Fuel Pump Serviced,Tappid Serviced,infact car is tuned perfectly.CNG kit i have already removed.

But recently i am facing problem in the morning when i start the car and on the road for about 3 to 4 kms Car doesn't give any power and drives slowly and then immediately after approximately 10 minutes, it gives a little jerk and suddenly picks the power and it becomes so light and flys like a ferrari,

i am very happy with the pick after that,but in the cold start i;m facing this issue, kindly inform me if any body have experienced the same issue as this issue is getting on my nerves

Please change your battery with New one.

Battery is ok, i thought of replacing it,but battery mechanic said there is nothing wrong with battery.

which city are you in? and if you start the car, let it warm up and then go off, does it still behave the same way, or starts properly?

[pwuser156110487549]

I am from Bahawalpur,yes i give it a good time to warm but still the same situation for 3 to 4 kms,one thing i also notice smell of unburnt fuel during morning startup.one person told me that there should be an issue with Fuel injectors, i am not sure so i thought i should take help from this platform.

Check your fuel lines, does this only happen if the car is left to rest for a few hours?

[pwuser156110487549]

yes if the car stays idle for upto 6 or 8 hrs this problem starts,but goes away after few kms drive.As it seems something starts working when it gets hot.

check your return fuel line, it appears that you engine doesn't hold in the fuel and it goes back to the tank.

Assalamoalikum, hope u will be fine, today i finally sorted out the issue as u know was in total lock down for the last 3 to 4 weeks.

It was one bad ignition coil, i replaced it today and finally the issue was done and dusted. The previous owner installed a repaired china ignition coil which was giving the issue. I thought to update you on it.

Thanks for ur concern and support.
