Question about 2003 Chevrolet Cavalier
HI. The first area of concern will be the fuel filter. If this component is clogged or restricted, it will not allow for proper passage of the needed fuel to the injector assembly. I would recommend to replace the fuel filter asap, if not done so already. Next area of concern will be the Positive Crankcase Ventilation Valve and corresponding hoses. Make sure that the hoses are not collapsed, and there is nothing blocking the valve, itself. Replace the valve if faults are present ,or if the valve seems to be stuck in one position. Another area of concern will be the actual air filter. A dirty air filter will cause acceleration issues, as well. This is an easy inspection and can be done, visibly. Simply remove the air filter from its housing and, visibly, check the paper based filter for contaminants. Replace the filter if needed.
Now, if all is well with the above areas, move on to the injector assembly. one or more of the injector(s) may be clogged or damaged. In this case, proper inspection of all corresponding injectors will need to be administered. Replace any injector that is not pulsating correctly, or not spraying at an optimal level. Also, check the connections at the injectors for proper fit. re-seat, if needed.
