My car is jerking.... why???

Question

I park my car in the morning and take it again in the evening. When I give accelerator it does not raise or move, instead it jerks until I raise it for some time and the engine becomes warm. After sometime it is OK... but I am facing the problem when I start the car after a long time - say 8 to 9 hours. Mine is an Opel Corsa 2000

Answer 1

Someone suggested a thorough tune up and they are right but it sounds to me you have a mixture problem -- When the engine is cold, before it reaches normal working temperature, you need to enrich the mixture a little WITH THE CHOKE. Chokes were always manually operated at one time but nowadays they are automatic. As the water inside the engine warms up it acts on a thermostat which opens or closes the choke making its operation "automatic" ie it will look after itself. When you press the gas more air enters the combustion chamber which is NOT accompanied by the equivalent mount of opetrol because the choke is stuck and is not working. Too much air, not enough fuel in the misture and the car jerks and goes no where. I say you need to look at the CHOKE mechanism. Stuck in the open position ? Actually you are lucky. It is better if it is stuck in the open position rather than in the closed position -- that way the engine would work fine until warm and then it woudl just stop.

Answer 2

this could be brought about by many issues. Your accelerator pedal sends alerts to the gas injection platforms by laptop. The injection equipment would want cleansing. The emission administration equipment additionally would desire to play a factor (blow-returned rigidity) The gas equipment is so complicated, i'd recommend taking it to a broking and characteristic them plug your motor vehicle into the diagnostic device. If this situation began such as your final gas fill-up, deplete the present gas, then fill-up with gas that has the backside quantity of ethanol. Use top classification standard or top classification gas. If this has been an on-going situation for a on a similar time as, i'd take it to a GM broking. in case you rigidity in particular around city at low speeds, take your motor vehicle for a fifteen mile highway spin at greater speeds. you could likely rule-out the brakes.

Answer 3

Sounds like your car could use a good tune up. Try replacing spark plugs, plug wires, air and fuel filters. I am not familiar with Opel but if it has a distributor cap and rotor button replace those too.

Answer 4

The problem areas could be - Your fuel system (line and filters), some times the fuel itself amy be bad ,Spark plugs, engine tuning etc.. Better to show to agood mecahnic. Take petrol only form a relaible and same source.

Answer 5

It is due to failed ignitions resulting from improper settings of plug gaps, bad compressions, timings, hence improper atomisation, insufficient or excess air than that which it is designed for, insufficient or excess fuel than what it is designed for, -any one or all of above leading to failed ignition initially, till the excess fuel (resulting from the failure of ignition) remaining in the cylinder is burnt up or purged out.
Your vehicle engine settings should be checked by an expert on your model and reset to manufacturers specifications.

Answer 6

It could be low on transmission fluid if it's an automatic. It takes a little time for the transmission pump to pick up the fluid. Hope this helps.
