P0507 - za wysokie obroty na jałowym

[mlody]

Wymieniałem wtryskiwacze gazowe i był zdejmowany kolektor. Po wymianie mam wyższe obroty na jałowym około 1000 i zapala się błąd p0507. Silnik nie schodzi płynnie z obrotów - na luzie przygazuje to zatrzymuje się 1500-1800 i po chwili schodzi na 1000. Czy gazownik mógł coś źle złożyć?

P0507-IDLE SPEED HIGH PERFORMANCE
When Monitored: Engine Running. During an idle condition.
Set Condition: If the engine RPM does not come within a calibratable high limit of the
target idle speed, a failure timer will increment. When the appropriate failure timer
reaches its maximum threshold without sign of RPM trending towards control, a soft fail
is generated. When a calibratable number of the soft fails is reached, a 1 trip fault is set.
When two 1 trip faults occur in a row, the DTC is set and the MIL illuminates.
POSSIBLE CAUSES
GOOD TRIP EQUAL TO ZERO
PCV SYSTEM
IAC MOTOR PASSAGES
VACUUM LEAKS
AIR INDUCTION SYSTEM
THROTTLE BODY AND THROTTLE LINKAGE
TEST ACTION APPLICABILITY
1 Ignition on, engine not running.
With the DRBIIIt, read DTCs and record the related Freeze Frame data.
Is the Good Trip Counter displayed and equal to zero?

Problem rozwiązany.
Kolektor został za mocno dokręcony. Przy dwóch spilkach przy podkładce zrobiły się małe pęknięcia.
Odkręciłem szpilki, podłożyłem podkładki o większej średnicy - zakryły pęknięcia.
Odpalam i
Obroty wróciły takie jakie powinny być. Wszystko działa dobrze.
Będę kontrolować, jak coś będzie trzeba gazownika o kolektor ścigać.
