I own a 2006 daewoo matiz, euro III, 68.000 km.
I have an issue with this car wich so far I was not able to fix my self or at service.
The problem starts at the first engine start of the after a long parking(minimum 8 hours). The engine starts fine, but after a few seconds it starts to choke, drops rpm(even stops sometimes).
NO error codes are stored in PCM memory, wich makes this very tricky fix.
So far I've tried:
-replacing spark plugs and wires
-replacing PCV valve
-cleaned IAC valve(with Idle Lear procedure)
-cleaned EEGR valve from deposits
-cleaned oxigen sensor from deposits
-tested TPS voltage
-tested car with Daewoo Tools Scan 100(nothing is wrong for the PCM)
and that's were I runed out of ideas here, so if you have any advice on this matter I woul appreciate it. Have a good day!
