Problem with a SKODA FABIA 2001 1.4L

SKODA FABIA 2001 1.4L 16V

Engine management light on and engine hunting on fast idle.

Fault codes stored P1553 map sensor fault, P1151 bank 1 long term fuel trim. Map sensor, front oxygen sensor, coolant temperature sensor replaced, throttle body cleaned and reset and valve timing checked, fault not cured and fault codes still present. Emission checked and excessively high on fast idle CO 7.57% HC 1650 lambda 0.750.

The fault was caused by a faulty EVAP unit, modified EVAP unit fitted, fault cured.
