A few weeks back I have been having a few problems with the car - Whenever I put the AC on the pickup drops drastically and car climbs speed very slowly. Also if the car is loaded with 4 people it really takes time in building speed. The AC works fine and everything else is fine. I got the car serviced around 4000 kms back and would get it serviced very soon again.

I finally took out some time and went and gave my car to an expert mechanic [...] Here is what he did -
Oil Change - 650 Rs.
Oil Filter - 100 Rs. something
Air Filter - 150 Rs. something
Fuel Filter - 70 Rs.
Coolant - 340 Rs.
Service - 300 Rs.
Injector CLeaning - 100 Rs.
[..] the pickup problem still has not been solved ... |
Here are some possible things you can try.
1. Are your Michelin tyres of stock size or are they upsized? This will have some impact on pickup. I would recommend stock size for Santro, as Michelins have plenty of grip already. Also check tyre pressures. You should set them accurately when cold and I suggest you keep them above the recommended 30 psi (say, 32 psi for city, even higher for highway drives).
2. The petrol you are using will make a big impact. Adulterated petrol can badly affect pickup/top speed. I recommend (unadulterated) Speed or some equivalent premium fuel, as this will minimize the carbon deposits and keep your engine in good shape.
3. You can also ask the Hyundai guys to do throttle body cleaning, in addition to the stuff they have done.
4. Go to an authorized Hyundai dealer and get them to check the engine tuning (in particular, is the ECU working correctly?).
5. I suggest you take your Santro on a couple of highway trips too. I have a gut feeling that the ECU will perform better if you push the car hard occasionally, rather then just confine it to city driving.
6. Is your clutch OK? I am also wondering if bad wheel bearings can affect the car's pickup; I haven't changed mine for about 30000 kms now and I am getting a bit fidgety as Sanjay Hyundai keeps telling me they are fine.
My old (1-lit) Santro has done about 73000 kms now. I am using Speed 97 plus alloy wheels plus overinflated tubeless tyres (stock-size Turanza ER-60 at 36 psi). Also Sanjay Hyundai does throttle body cleaning at each service and I do engine flushing every 10000 kms. The car has terrific pickup, and the engine seems to be more or less at its peak now. Several Xing/Zen guys who challenged me have found my old Santro to be more than a handful. I think the wheels/tyres/pressures/petrol make a world of difference and it is a different car now.
