Guys,
My FG seems like its lost some punch... was wondering whether the spark plugs could be causing this drop in performance.
The car has done around 126,000KMS and the plugs have never been changed...could the plugs be causing this lack of acceleration urgency?
I always assumed worn plugs would missfire etc...
I also have read that with new cars the voltage can be increased to accommodate a worn out spark plug...
I have ordered genuine ones from Ford, but they seem to be scarce at the moment and no Ford dealers currently stock them. (they're on back order)
Is there anything else that would cause a gradual decline in performance?
