Hi everyone, ok so i've been having some problems with the focci, driving around town or short runs she runs fine, idles perfect etc ....
When i take her on a longer run say 100 miles+ she starts playing up, normally after i have slowed down for a round about, when i accelerate after a round about or after slowing for traffic she starts kangarooing jerking and slowly decreasing in speed until the point that i can no longer accelerate past 20MPH, so i pull over and switch her off for a couple of mins then she goes again, but not for very long, then she'll start playing up again.
So far i have give her a full service, changed the coil pack and HT leads.
I've plugged the scan tool in and she isn't storing any codes.
I've checked to see if she is getting a vacuum in the tank, by opening the fuel cap with the engine still running, but no pressure is released.
Everyone i have spoke to has no idea what the problem is.
Can someone kindly please help me out with a solution if possible.
I'm planning on taking her down to Cornwall in two weeks so any help would be much appreciated.
