I've recently bought a used City Vario 2007 106K mileage. Got it checked when buying and it was perfect in running etc.
I got it through a reliable dealer (dealing with him for the last 10 years). Asked him to get the car serviced before delivering to me. When he brought car to me after service, said it is 'missing'. Some water might have gone in and it will go away in like 2-3 days.
I started using it and soon realized that engine was not missing (started and checked at different accelerator positions, cold/hot). Checked it by mechanic and there wasn't a water issue in plugs/coils.
The 'missing' referred to is as follows:
- In the morning, when I start the car, the RPM is at about 1.5K+, stables to about 1.1K or lower in a minute. I think this is normal.
- Putting the car in D takes the RPM back to 1.5K+, gets back to normal within 2-3 minutes of driving. I think this is not unusual as well.
- When I try to accelerate by pushing the paddle, the car takes jerks, RPM goes up and down. It stabilizes after a few seconds.
- The jerking and RPM variation is directly proportional to the intended acceleration. I.e. if I am (nearly) stopped and press paddle, jerking happens. If I am going at like 20 km/h and wants to speed up to like 60+, jerking happens.
- The jerking does not happen when I have paddle pressed more or less in the same position and car accelerates gradually to a higher speed. No problems.
Got valve body service service a day ago. Things are slightly better but jerking has not gone completely.
Mechanic said if jerking does not go away, transmission will have to be changed. He said Japanese Honda City transmission could fit in local Vario after some alteration. Claimed he has done it many times successfully. Total Cost is 25K. (Mechanic: Shahid from General Motors, near Chandni Chowk Park (Karachi).
I've recently bought the car and have obviously spent a lot of money in buying it. Don't want to throw away money unnecessarily if the problem could be solved with little cost but with near 100% RELIABILITY (in Karachi).
I don't know if this information would help. I drive the car daily (7 days a week, 5 days to office, rest for household work, outing etc.) and my average running per day is about 40-45 KM (about 1300-1500 KM per month).
Could someone here please guide me how should I go about solving the issue. I must confess that I know very little about engine and transmissions. Please consider a layman when giving your advises.
