Hi
I have a 2004 manual 1.6lt Spectra. My problem is the car has very poor acceleration between 1000-2500 rpms and shows very late responses to the gas pedal. It hesitates for a few seconds and starts to accelerates weakly. On higher rpms it goes pretty well and there is no problem when idling. None of the check engine or check oil lights has illuminated. Any idea about this problem? Thanks...
