my 2001 hyundai elantra runs fine, then decides to die out, then it wont start for a while, then runs fine a day or two then die. i bought a scanner and these 9 codes came up. (its 4 cylinder, 5 speed.)
P0301 (cylinder 1 misfire) (generic code)
P1440 (EVAP system vent circuit malfunction) (manufacturer code)
P0443 (EvaPorative emission system purge control valve circuit) (generic code)
P0303 (cylinder 3 misfire) (generic code)
P0304 (cylinder 4 misfire) (generic code)
P0302 (cylinder 2 misfire) (generic code)
P0300 (random misfire) (generic code)
P0507 (idle air control system RPM higher than expected) (shows up 2 times) (generic code)
all codes show up in this order, i dont know where to start. what should i fix first? could one thing be the cause of the other codes? whats wrong? any help would be greatly appreciated.
