This coil rubber boot needs to be checked.

In case these rubbers have completed their life the spark/current shall be lost towards the cylinder head, causing misfire.

Also check Idle air control valve. Hopefully throttle body has been serviced during the last maintenance?

[taimurahmed92]

Did you use brand new coils or kabali coils? Kabali coils are mostly busted.

If you used new coils and the car is still jerking then it can be many things which you can check one by one. TPS sensor, Map sensor, o2 sensor, earthing wires, camshaft sensor and crankshaft sensor.

Mostly the missing issue is due to coils, TPS, map or o2.

Kabli coils

[taimurahmed92]

If you have a multimeter (borrow from an electrician) you can check the resistance of the coils and wires. The test you can look up in the FSM. Link is in a separate thread title "Dewan Lancer Manuals". Download the whole FSM folder and then open the Start Here file. Then go to the index and look for ignition coils chapter. The testing process will be given there.

Hi, people I am new to this forum and new in the Lancer club, As I have bought a lancer 1.5 CVT auto. I am facing an issue in it. Sometimes when I shift the gear in idle position the car RPM starts to drop and when turn the steering to take a turn in D or R the car Rpm drops and starts to vibrate. Otherwise when I accelerate it their is no such issue in the car, runs fine at the time. Any expert suggest me that what might be the issue.
Thanks

Seems like a failing idle motor or a dirty throttle body.

[uzairahmed23]

Thanks for the reply @taimurahmed92. Where is the Idle motor located?. Also I am facing another issue when I drive the car in lower RPM's when the gear of the car shifts I feels some jerks in the car. its feels like the car is missing with some constant jerks but they are minor jerks. Not a very strong one. And please if you know any good mechanic in Lahore for Lancer please provide me its contact number.

[taimurahmed92]

I'm in Canada so can't link you up with mechanics but for missing it can be plugs, coils, injectors, fuel filter, fuel pump, map sensor, o2 sensor.

Idle motor is mounted onto a metal housing just underneath the throttle body.

For gearbox shifting, check oil. The cvt uses only mitsubishi atf sp3 oil. For a full oil flush there's a separate thread which you can look up. I believe it's titled 2005 lancer cvt oil flush or something like that.

Can be due to vaccum leak or transmission.
@syncview is in lahore you can visit him.

[uzairahmed23]

Thanks @taimurahmed92 for your help. I will get them checked. I am finding where I can get original transmission Fluid from Lahore. I will check and inform you if my issue is resolved.

[taimurahmed92]

Check with Usman Autos Lahore or Mansoor Autos Faisalabad

[uzairahmed23]

Yes, I asked from Usman Autos. They had Mitsubishi AFT SP3 oil with them. But I got the gear oil changed from a shop near my house. I used Liqui Moly It was expensive than the Mitsubishi one. It was also recommended for Mitsubishi ATF SP3. Transmission is a bit smooth now and jerking issue is now very less. The old gear oil was very dirty. Therefore Got the transmission flushed before with fresh oil. it costed a bit high but issue is very much resolved.

[uzairahmed23]

But one issue I am still facing is when the car is cold and then put the gear in D or any forward gear and move it. I feel a "Grrrrr" sound in the gear just like agar bike ki Chain bohat tight hoo tou you hear a Grrrr sound when moving it. Just giving an example, I hope u can understand the noise the gear makes. But as car gets warm and travels a bit it gets fine and no such sound comes or feels in the Gear. I think their is some kind of Gear Belt issue which is inside the Transmission or might be the oil isn't flowing in the Gear properly when I start the car when its cold. Should I get it checked to a good CVT Transmission mechanic or drive it like this?

[taimurahmed92]

My personal recommendation is to use oem fluid only for gearboxes of any car. The gearboxes have become quite complex and there are small differences between same atf sp3 blends of different manufacturers. Liqui Moly is very good and I use its engine oil, coolant, brake oil and PS oil in my lancer. But I only use Mitsu ATF SP3 in CVT.

As for your gearbox noise, I doubt it's the gearbox if the noise only comes when the car is cold. Could be something else. Oil pressure issues in the gearbox will usually trigger a flashing N light and error code. Did you drain and refill the oil with around 5 litres or used the complete flushing method with 8-9 litres of oil?

[uzairahmed23]

Yes, I was going to add Mitsubishi Oil. But unfortunately couldn't get hold of the gear oil. So got it changed from near my home. Next I will get the Mitsubishi oil changed a bit earlier than recommended Km's. I also got it flushed, it was used around 8 liters of oil. But they didn't open the filter part. As the person was saying it might create more issue in the gear. But I have heard that its best to get the filter part opened and also wash the magnets inside it, didn't knew about it before. There is no flashing or Error Code showing yet. I will get it checked to a mechanic. Please suggest when to change the Power Steering Oil. I actually don't know the actual millage the car has driven with the power steering oil.
Thanks
One more thing a constant whining noise comes from the back of the car as if some electronic component is working when the car is start, Don't know from where the sound comes. just like hybrid cars main sy joo awaaz aati hy when they are running on battery mode.

[taimurahmed92]

For the sound you’ll have to get a mechanic to diagnose with a stethoscope to pinpoint the exact culprit. Could be rear wheel hubs. They come as a sealed bearing assembly so the whole hub has to be changed only.

If you’ve flushed the oil then your gearbox is probably working fine.

[uzairahmed23]

The hubs were changed by the previous owner, I they are working fine. But the Whinning noise comes even when the car isn't moving and is only kept start. Just like in EFI cars jub app switch lagatay hain tou for 2 -3 seconds you hear a whinning noise that I think is from the fuel pump. Overall car is working fine just need to get it checked and tuned from a good mechanic. The pick up of car is very slow and when I push the accelerator hard it makes loud engine noise and afterwards it gets smooth. And one more thing sometimes when I shift the gears in D or R I feel a little jerk in gear. but sometimes its very smooth in shifting. Does the CVT transmission has this jerk bulit in or their is any issue in the gear?

[taimurahmed92]

These are early CVTs so noisy. Share a video sometime of driving the car at 2k and 3-4k rpm. Slow pickup needs investigating as it's a pretty agile car.

For shifting jerks you should get cvt oil flushed. You can check the oil color on the dipstick on tissue paper and share here.
