Doosan (& Daewoo) GC25E-3:
HEEELLLLLLLPPPPPPPPPPPP!!!!!!!!!!!!!!

Ongoing isues with GC25E-3. Did Head job in February. 15 days later: Coil pack, temp sensor, cooling sensor and wire repairs due to complaint of suddenly stoips while driving. May -Engine light, smells bad, idles but no drive power. Even sent a video of it. Replace Vaporizer, MAP sensor, fuel filter, carb kit. Running good. Now July same complaint, Smells like eggs and no power. I have never been able to duplicate problem this whole time, but have found other issues. Replaced Throttle Pot and Throttlebody due to runnning sluggish and delay between throttle application and RPM climb. Engine light still comes on mid RPM. I am lost! Any ideas would be greatly appreciated.

Turn key on, depress accelerator full stroke 3 times in less than 5 seconds and then watch the check light and read off the code(s) stored in the SECM. Codes are 3 digits except Code 12 which means end of codes and it will then repeat from beginning. Post codes here. Also is this the Hyundai or GM engine?
