My car has 3 problem that no one is able to diagnose..
Its a baleno EFI 99 G13B
1) the check engine light on startup should show for few seconds but since 3-4 months the light sometime lights up and sometime doesnot, showed it to an electrician and he checked the car ECU, instrument cluster for loose connection or loose bulb but was not able to find it..
2)On start up there is a very sharp squealing type of noise from the coil pack area of engine but its not the fan belt.. My car has 2 coil packs with provision of 2 2 ignition wires each.. . the sound is there in extreme cold and slowly disappears when the car warms up.. the oil light only shows up on start up , so oil pressure may be normal. 1 year ago an electrician told me that alternator needs replacement. when i turn on the indicators the handbrake light blinks with the blinking indicators. The battery light only shows at start up..
3) there is a persistent dull growling sound from trimming belt area in idle.., timming belt and bearing were changed 16000Km ago.
plz help @ Xulfiqar bhai
