Battery terminals checked and cleaned with brush and baking soda.

 

You may want to try a bottle of Caltex Techron Concentrate to clear the fuel system and injectors.

No loss of power during acceleration. Once accelerated the vehicle perform normally.

Quick update.

 

After a quick DIY ATF Change accordingly to repair manual guide.

 

Vibration without aircon for D N And P Reduced nearly 50percent. However R mode is still the same as before.

 

Gonna check the ignition coils and spark plug in the upcoming weekend.

Does you FC becomes higher lately?

If yes most likely one ignition coil or one spark plug is faulty

Need to plug in an OBD to see which one is faulty.

Bought a new ignition coil to perform some troubleshooting.

 

May I check with the experts here. Is there a possibility of 2 ignition coil going bad at the same time? So far I only bought 1 piece and going to use the try and error method to check for the symptoms.

if 2 will be badly vibrating and stall likely..

that's why car min is 3cylinder package, with mild vibration at low rpm, only stable at higher rpm

How about changing your fuel filter.....cheap but can cost a lot of headache if choked!

If I never remember wrongly, saw it from the repair manual, suzuki’s Swift fuel filter comes together with the fuel pump which I saw in the diagram it’s inside the fuel pump. Last time I got a quote to replace both the pump and filter cost 1k+++

First tank of ron98 petrol in this vehicle. Previously was all using ron95 and ron97 from JB.

 

1) it was right, the user manual recommended ron98. The engine was much responsive as compared to ron95.

 

2) vibration went down even further, the jerk when the car is slowly down to 0km/h is almost gone. However idling at D and reverse mode vibration is still present

Mine COE car, after change PCV value & reset ecu. Now better.

 

Hope it help

Engine mount will actually affect idle RPM causing the car to choke for air?

Cause vibration. You mentioned reverse vibration is higher which might indicate the front or rear mount is collapsed.

 

Oh zc31, you need 98. Only zc32, 95 octane is ok.

RPM goes down 600 that is causing the vibration. Can vibration with faulty engine mount cause the rpm to drop?

The user manual states 98 is preferred. However when 98 is not available, it is ok to pump 95. Didn’t expect it affect the response so greatly

Seems ok to me. The deposits looks like they are from the fuel injector cleaner.

 

Are the plugs the correct model and heat range?

In this case, it wouldnt be spark plug issues. Other 3 plugs are in better condition than the one pictured. 

No cracks or whatsoever

 

Yea the plugs are Denso IK20 recommanded by Denso's catalogue.

 

I just use techron a month ago. That explains the color. 

I have order the following item to try and error for the next weekend :)

 

02X ignition cables. 1 long 1 short

01X ignition coils. My vehicle has 2 coils however I doubt 2 would be faulty at the same time

How long have the plugs been in? I guess they are still cheaper to try than coils.

From what symptom did you conclude that the engine choke for air ? Did the engine die off at any instant ?

In fact engine vibrates all the time but it vibrates more when rpm is low, and a good engine mount would eliminate such vibration especially when the rpm is low.

The vehicle RPM drops to about 500-600 when in reverse mode.

I don't think that is a healthy RPM range when a car is engaged in reverse mode.

 

When it is in Idle mode, it's RPM also in the range of 650-750, slight vibration can be felt

 

Today morning I left the vehicle engaged in reverse for about 15 20minutes. It did not die off though but engine is vibrating badly as seen from outside

How long have the plugs been in? I guess they are still cheaper to try than coils.

 

About 1-2 months. Less than 5000km

your RPM drops  to 600 when your gear is  engaged is normal, that is because when gear is engaged, the transmission is adding load to the engine. It is not a faulty mount cause the RPM to drop.
