Dear Xulfiqar
My daewoo with G15MF engine fitted with 3 speed auto transmission i need to release the gas pedal at 3-4k RPM to shift from first gear to second and from 2nd to 3rd is this normal or i need to worry about? or i need to change the oil? or something else?

[Xulfiqar]

your vacuum modulator is dead. Replace it with a new part

[overspeed111]

Sir thanks a lot, it will be a hard to find this part here as automatics (hydramatic) daewoos are very rare over here, cleaning DIY of vacuum modulator can do the job if i cant find replacement?

@Xulfiqar Bhai, need your advice for my Indus Corolla 99. where can i find a good mechanic for tuning?
my car sometimes give 12 km/ltr average and some time it gives 6-7km/ltr.
also i have witnessed sometimes (not on regular basis) there is a blue smoke coming out from the exhaust.Although got its ring piston changed last months but issue is not resolved yet.

Also i think engine is buring oil too. there is no leakage in the engine room.

sir today i did the DIY and get to know that vacuum modulator is inside gear box cant be replaced from outside seems like a hefty task to do this and also i do not have expertise to open a auto transmission, i ve replaced the vacuum pipe and sprayed carb cleaner but yet no effect on that.
thanks for your guidance.

Salam. I have purchased Suzuki Cultus 07 Carby model. The car is above 1 lac but the meter says 68k. The engine is fine. No major work required on it. I will only change all the oils, spark plugs and clean the radiator.

I have drived it for a week and I think the engine has not a great fuel average. Should I change the air and fuel filters for this purpose?

I also need to ask that which engine oil will be best for my car in winter and in summer.

I am really confused. Some guys say to use 20w50 as the engine is old while some suggest 10w40.

Please suggest me the best engine oil.

Salam brother. I have Civic 1999 vti. In december the engine blown up due to heat up. this was the 2nd time. I swapped the factory fitted D16y8 with the D15B. swapped just the assembly. all other items I used are of D16y8 like Manifold, sensors, throttle body etc.

I'm facing the issue of unstable RPM. it goes to 1100-1200 then drops to 0. many times engine shutdowns. I've changed the autochok but in vein. Can you please help me in this regard. or you can suggest a good mechanic (not thug) in Lahore who can resolve the issue. Thanks.

i have a 2011 Crusetronic Altis 1.6, need to know from where, except Toyota Workshops, i can get a good and quality service, like lubricants change and tuning etc, i feel in past few days, on idle, the RPM is going up and down a little, seems like some electrical issue or needs tune up?
please advice.
thanks.

[sameerulhaq064]

Kindly mention city.

[aliashraf78]

sorry, Karachi.

For unstable idle with engine 2aed up, throttle body cleaning should be done. I prefer throttle body cleaning without removal with liquidity throttle body cleaner. Also, carry out replacement of spark plugs and change of air filter.

@Xulfiqar

Salam dear, I recently bought a passo which is now struggling to take acceleration at low speed also vibrating, need to press hard the acceleration padle to get boost and than fine after that, acceleration is also fine while reversing. I have checked with mechanic and he is saying seems your engine is weak and not transferring the power to wheels, I asked why it is normal with reversing but he has no answer. please help me to resolve the issue.

@kingofmb

symptoms are

1. low transmission fluid
2. choked cat converter

check from previous owner if they have changed the transmission fluid, the fluid change is required at 70,000 km if the odometer is not tampered and is genuine.

next is cleaning of cat converter.
