Hey you lot, I'm new to the forums, hopefully I can provide info as well as deal out the problems :) I purchased a '99 Mk4 Fiesta about 8 months ago and gradually the lower end of the gears, when I need to accelerate mid to hard it feels as if the engine momentarilly cuts out for a few seconds then around the torque band it sorts itself out. replaced the spark plugs a month or two ago and the problem ironed itself out for a while, but it has returned again! I bought some Redex for injected engines thinking its maybe a problem with the injector bank? Question is, is it my driving style? Or am I missing something important? Any questions just fire away. Thanks in advance, will probably edit to add things I've forgot!
