Hi gurus,
as the matter of fact I am very confused about a TC 55 (defective ECU) which I likely face almost in every Astra F with
C14NZ (1991-96) engines.
is that a really bad sign? cause the TC disappears right after the engine starts. Most of people whose car had fixed this fault complain of excessive fuel consumptions.
Any ideas?
thanks in advance,

Dilick
