I post my sincere appreciation for the advice and assistance, occasionally to myself but often to others, that has enabled me to fault-find and cure my 1998 2.0L DTH Vectra Estate when it would have otherwise cost me loads of cash.
It has stretched my elderly skills to their limits and beyond but the gaps have been filled in by information from this N/Group and enabled another good year from this vehicle.
Season's good wishes all round.
Tony.
