I have 2 cars bought in Oct 2002, both alto VXI. Both have done similar kms, 45k or so. One of them offlate has been very sluggish in accelerating on all gears. Also its mileage has come down to 12kms/l. Got the timing checked, injectors cleaned, compression checked, air filter changed but no improvement. Even at slightest of climbs I have to come down to lower gears ...some time at first if the speed is low ....where the other car races at 2nd or 3rd gears.

Any pointers as to what can be wrong? Should I get the timing advanced? I have always taken the car to Maruti authorized dealrship and they dont hav a clue as to what could have gone wrong with the car.

Worn out clutch, wheel alignment could be other reasons..

Everything points to a worn out clutch. Get it checked.

It cannot be a worn clutch, because if that case the RPMs would go up on hitting the gas but car would still not accelerate. In my case he rpms were also not going up.

Got the timing advanced by a degree and things look good now. Does anyone know if there can be a side effect of this on the fuel efficiency or engine life?
