Well l travel 80miles a day to uni! (40 there and back)

And l notice that sometimes my car will do something abit weird. The only way l can describe it is... when you do a dodgy gear change, the car will jult abit wont it?

Well thats what my car does in the middle of driving...What is it??

If ur car is jilting during driving it could be down to durt in ur fuel tank. If it does it more when u r running on below 1/4 of a tank then u will need to take it to a garage for them to flush the tank out to remove any durt. It can also happen if ur tank is full but because there is more fuel it tends to dilute it abit. l would book it into a garage though,this may not be the problem but this has happened to me before when l used to valet cars for a living. Good Luck with that.

Yes a dodgy gear change will do that, l assume the car is fine otherwise!

your missfire could be down to a faulty coil pack this will cause the car to jolt and pull back replaced a few on 1.0 lupos
