Ka engine 'hesitant' when A/C is on
I have just acquired a 1999 'V' plate Ka Millenium with about 50,000 miles on the clock and have a problem I would like some advise with, please.
The is when accelerating in 3rd/4th/5th with the A/C switched on. The engine seems to hesitate and distinctly lack power, especially when going up hills.
While the engine is hesitating, if the A/C is switched off, the engine suddenly gets its power back. Switching the A/C back on again, the engine hesitates again.
Other than this proble, the car is in very good order with a full Ford service history in the UK.
Has anyone experienced this problem before, and suggest a likely cause, please?
