Suzuki liana cold start issues.
I have suzuki liana 2007. Engine rebuilt at 220k. Ever since engine is rebuilt I have been having cold start issues.
Issue 1:
On cold morning, when I try to drive, the car jerks ALOT. Like alot. More jerking at around 2k to 3k rpm. The engine also takes a long self to start, giving a little bit accelerator makes the car start quicker.
Issue 2:
Also the car literally has no throttle response or power when cold. Doesnt matter if i give it a little bit of throttle or full throttle, the car woulnt accelerate when cold. And jerks alot between 2k and 3k rpms when cold. Both of these issues go away completely at operating temperature, but they tentatively reduce when even a little temperature climbs.Also, turning the car on for 1 min then off for 1 min also fixes the issue.
Issue 3:
Really rough idle when cold. At operating temperature when starting the car the idle drops really low but pumping accelerator two to three times fixes the idle. Also the car keeps stalling when at operating temperature while driving and pulling in clutch.
REPAIRS DONE SO FAR FOR THIS ISSUE:
ignition coils swapped, spark plugs changed, air filter changed, fuel pump with assembly changed, ect sensor cleaned and checked, map sensor cleaned, iat sensor cleaned, o2 sensor cleaned, no fault codes, throttle body completely cleaned.
Note that all of these issues go away at operating temperature except the stalling at time to time.
Please help guys this has been a big headache
