Got a 2000 1.0 polo engine code AER. very irratic idle, youd think it had misfire.
scanned with solus pro, showing fault code 01087 Basic Setting Not Performed.
throttle housing looked clean, tried throttle adaption with ignition on engine off at normal running temp
started car still the same running like a bag off bolts
Today Replaced engine coolant sensor as not corresponding with dash temp.
removed throttle body cleaned butterfly until spotless relearned adaption, but fault code 01087 constantly there, basic setting not performed signal outside tolerances, when you clear codes, it says cleared but when you go back into codes its still there. when you remove throttle plug it idles okay, when reconnect very irratic again.
As said seems like misfire, but scoped primary and secondry on coil, scoped disrtibutor hall sensor and leads, also injectors all showing okay.
injection juration 3.2ms lambda switching fine.
Was gona put throttle body on next, but its ongoing
