Hi everyone my matiz 3 wont start after I have parked for about 30 minutes. However, if I park for more that 24 hours, it starts at the first kick. Besides that, when the engine is running idle, it shakes and it has the check light on. I hv been to several mechanics but to no avail. Any help as to what the problem could be exactly?

Distributor not advance spark timing according to engine speed/rpm and making engine vibration during acceleration and deceleration. I have adjusted distributor setting with timing torch which was 5 degree according to engine manual but engine making vibration during acceleration and deceleration, when I adjust distributor 10 degree the car runs smoothly but the pick up of car is low. I think spark advance timing is not working, please tell me its fault about distributor, ECU or distributor adjustment issue. And how to check these issues.
