Running problems

  1. #1
    Still having cutting out problems with my saxo when it gets warm. have changed every sensor. its a vtr engine ive put in a 1400 shell phase 1. i had all the loom, engine and ecu. unlocked the ecu so it would run. after afew minutes from cold, engine light comes on and wont start again until its cooled down for afew minutes. its idling high and not running very well. the errors that come up are 'mixture control'. im assuming its all ecu controlled which is leading me to think that the ecu is at fault. does anyone agree? or give me any information that might help me with my problem.

    thanks in advance.
