My 2002 2.0L Focus Zetec is having power problems. I have taken it to my local ford dealership service centre. They ran a diagnostic which did not show any flags. They found pinging and ran a cleaner through the head which has improved that problem.

The other issue is that when accelerating the engine is not going as well as it used to or should. The problem is worse going up hills, and also seems to be extremely bad when in 2nd or 3rd gear going up hills (with foot to the floor).

I also found that the problem will occur when I am accelerating with my foot to the floor in any gear (even 5th on the freeway at 90km/h +)

If anyone has any tips or has encountered problems like this before any help would be appreciated.

My thoughts is that it is 'choking' and not getting enough air, but the service centre didn't find anything wrong with that as far as they could tell and the car has been logbook serviced for its entire lifetime.

95,000kms ODO or roundabouts.

Thanks
Focus owner
