I have a Fiesta '93(K) 1.1 CFI (push rod) engine with 85k on the clock It
will start and tick over fine but develops no power so top speed is 45-50.
I have changed plugs/leads/head gasket had the clutch checked for slipping
and put additive in the fuel - no joy. Does anyone have any (polite,
practical) suggestions on what to try now?
