Hello guys, have a 1.6-er Escort from 98 with Cetec engine with above mentioned problem – practically always holds in approx.5-second act – from shortly before going out up to about 1500 revolutions high. There is also no significant difference, whether cold or warm engine. Very rarely is idle as intended; e.g. if I give gas a few times (in the stand). Has someone had this and can help me further? Have tirefully removed the idle control valve, cleaned and measured and again a I think the motor control unit gets “not complete values delivered” – was read out with the result: Idle control valve (I just checked that..). Read here in the forum among other things housing ventilation valve – how do I check that then, electrical connection did I not see? And the Lampda probe? Or air mass meters (has someone measured for this?) Would I be happy about help
