Esteem jerky acceleration starting problem...help

[devp24]

Hi friends...i am having a small problem with my car (esteem 1998 model)...whenever I start my car...the start is very jerky...i mean the acceleration is not smooth...and sometimes if I dont give much acceleration the car stops...so usually I keep the accelerator pressed for sometime whenever I start the car ( i guess its done to warm up the engine)...but the jerky acceleration is there for few minutes after the car start moving...later on the drive is smooth....no jerky acceleration after driving the car for few minutes...

Is it a problem of the engine not getting hot quickly or some other problem...it will be really helpful if u ppl can help me find out the cause and suggestions to rectify the problem...

thanks in advance

I think its the Starter motor and Ignition Coil that need to be checked, But the 1998 Esteem had a Distributor right and Carb.

In most cases rough accelaration is due to these parts at fault till they don't warm up and The Plugs can be checked out too.

Other than that,since the car drives good after the intial warmup,I doubt anything else.

Clean your air filter. And as suggested by wolfinstein, get the plugs checked.

Change the condensor and point in the distributor, put a MGP replacing it.

Guys i think he has a perfectly set air/fuel mixture because of which during cold starts the engine needs a richer mixture and he must be depressing the accelerator way too much to get the proper power but since the air/fuel mixture is the same itself the jerks as the engine is not able to deliever the power as its cold.
And since the engine after attaining the normal working temperature works properly he has nothing to worry about.
I bet my life on it that he must be getting good mileage
This is a small price u pay for getting power+mileage.
Also it can be a 'almost jammed' butterfly in the carb

get complete engine tune up done, including carb and filters.

Since yours is a carb Esteem,and you have reported this problem in Dec,it is because of the low ambient temperature and as a result,colder start ups.The Esteem motor is an aluminium alloy one..so expect the engine to get much colder than other engines.I faced the same problem in my '95 Esteem when I used it here.

Since you have reported that the jerks stop after sometime,I think you should not worry..just control your acceleration till the engine temp. gauge shows a little over the lowest mark.Then observe for jerks..it would have stopped.

Please check this and revert.

thanks a lot for your replies frends......the carb and engine tune up was done some times back....that time the mechanic had not tuned the enginer properly and the car used to stop a lot...after tuning it again the problem was reduced but still have the startup problem....

i will try to carry out all the suggestions provided by u all and hope the problem ends or minimizes at least.......

thanks again
