Erratic idling on Omega? - vauxman
I have a 1996 2.016v Omega and it has developed an erratic idling fault to the point where it nearly stalls then races up to 2000 revs. The idle control valve has been removed, cleaned out and re-fitted. (could this still be faulty?). The breather pipes are clear.
On travelling at around 30/40 m.p.h it tends to hold back then pick up then hold back and so on.
The fuel pressure valve fitted to the end of the fuel rail "hisses" as if its leaking air? The car also "pinks" on acceleration too. so does anyone have any ideas before i burst into tears?
