I used to experience in my Amby of 1973 vintage and that too only in the cold climate of Delhi. I used to start it with the choke pulled on and without touvhing the accelarator it used to revv at high rpm. Then slowly after about a minute or so, I used to push the choke back and then slowly move forward after engaging the gear.

I do not know about the MPFi engines coz the last petrol car was a carb esteem of 1999 and it too used to require the choke assist in the winters. The diesels never posed this problem for me. Half self start the first thing in the morning and just vroom ahead..!!!

If I do not wait, the car jerks like crazy and hardly moves. I have no experienced this with the Wagon R - which is ready to go almost immediatly.

I keep my lancer petrol (2000 SLXi) idle for 30 secs & Lancer diesel (2003 GLXd) for 10 mins every morning

What you saw reported were for cars with fuel injection. In a fuel injected system, the ECU runs the engine at a higher RPM when started and then it settles to the correct idling RPM.

In a carb engine, there is a manual choke for assisting cold starts. If you use the choke, the engine will start in a higher RPM.

But still, I feel your idling at 1000RPM is higher than needed. It should be closer to 800RPM. get it adjusted. It should improve your fuel efficiency.
