My ford focus is misfiring when I am at low speed in a high gear when attempting to pick up speed. When the revs are high this does not happen can anyone help.
i have had the coil pack and ht leads replaced twice in 6 months - garage said the first batch were faulty - duh! they apparently had problems with other products from same supplier at same time! im pulling my hair out!! help!!!

Usually the spark plugs, just had the same on our Focus 1.6 2005 model. If yours have already been changed then it may be something more sinister unless they were not set right the 1st time.

sorry yeah the plugs were done aswell! no the light isn't on!!

Coil packs are a real problem with these...is the engine management light on? Replacing the spark plugs could help too - you don't mention if this has been done.
