Baleno 1.3 G13BB RPM Dropping Issue

[index031]

Aoa,
I have 2005 Baleno JXR. It was driving Flawlessly until a Month ago. After a Long Drive it all started. The Car Started to Give Jerks On every Gear Even on High Rpm (4000 rpm) Whether Its 1st Gear or any other Gear. The Rpm Fluctuate When Clutch is Released and Touches 0 and car turns off and keeps fluctuating. On Idling its Normal. But this Problem disappears when car reaches optimal Temperature. The car used to start on First Self Try but Now it takes long Self to Start.
Experts Kindly Help me Out.
Note:
Car is Always Driven on Petrol and Cng is never used.

please check if your map sensor is properly connected.

[index031]

Yes I have Got Map, Crank and Air Filter Sensor checked and they are OK

i had similar issues in my baleno 2004 ff cng model. the works i did time to time made it a treat to drive:

1.timing of vehicle gets disturbed if the lower sprocket is bad - and it really makes the drive miserable
2.i rectified all the wiring of vehicle - advancer/emulator/main harness was taken out and all joints/tapings were removed - electrician charged 6000 back in 2019 and car was perfecr
3, this car is notorious for crank sensor issues - did you get hit from front right side or water submerging
4.MAP sensor's small pipe was once out and this simplest of thing made the car undrivable.
5. change of new plug wires
6.battery terminal change

connect it with scanner if it had OBD port at some suzuki 3S centre and check where its malfunctioning

if not you need to go step by step to check all sensors/firing current / timing and fuel pump to know real cause

it could just be crank sensor which is common issue in these engines

[abacus]

please check fuel pump and filter.

Its Not Showing Check Engine Light.
Can the OBD scanner still trace the fault?

[index031]

My Doubt is Also same will get its Pressure checked.

[index031]

Thankyou for Your Response.
Secondly my Mechanic is Saying to get Throttle Body Serviced. What do you think about that?

[SER_GTR]

suzuki 3s shld had scanner tools to connect and know if scanner port is intact...

[abid110]

Saying to get Throttle Body Serviced

this is a typical thing suggested by all mechanics to make very easy money and this will not solve your problem.

[index031]

The Port is Intact and will get it scanned after checking fuel pump pressure

Update: (Problem not Solved)
1. I have Changed Cam Sensor Grip and **MAP
Sensor Grip** as they were not in good condition.
2. Got OBD 2 Scanned by Computer there were no
Fault Codes.
3. Fuel Pump pressure checked and its Above 40 (OK).
4. Fuel Filter was replaced year ago (but still got it
checked) and Injectors are Checked and they are OK.
5. Checked Crank Sensor (OK).
6. Throttle Body Cleaned (but was not removed)
7. Spark Plugs Wires Also Changed.
8. Electrician also Sanded (ragrai) the tips of Coils and
Previous Spark Plug Cables.
The Car drived Flawlessly for about a week and now the Problem is again back. Experts Kindly Help. I will be thankful to you.

How much battery voltages ecu displays on obd2?
How did you check the crank sensor?
Clean each grip of all sensor.
How did you check the ignition coils?

[index031]

I dont remember the Battery Volts but I have put a new Dry battery 6 months ago and it is showing green indicator.
The Crank sensor is located under the car the Electrician checked it by removing grip and said its OK
The Ignition coils Bolts were removed and Car was Started. The engine started missing when coils were taken out slightly. Electrician told that they are OK.
Today I went to another Electrician He removed the Throttle Positioning Sensor (TPS) Grip and asked me to drive the car without it and give Feedback. I drove the car and the car didn't jerk once and was not even shutting off on slow rpm (But I was not sure it was still the TPS because the Car would leave jerks itself and again they appear) So I connected the TPS Grip again and Car is running smooth again. Cant Understand what's the problem?

[Hassan1991]

Grips of suzuki usually get rusted and need to be cleaned. Also it power loss problem in wiring because of which voltages drops to ecu causing multiple problems.

How to Clean Grips?

[Hassan1991]

Use contact cleaner spray.
