I recently left my 1.3l V Reg (1999) Ford Fiesta in a damp field overnight (I was taking part in a bike race!) and that night it rained a lot. The next morning I was driving home and discovered the car had developed a stutter / kangaroo / judder (or whatever you want to call it) at low to medium rev's when you accelerated.
Research pointed towards the fuel filter, spark plugs and HT leads. The fuel filter was the cheapest item at under £5, so I replaced that first. The fuel filter is located on the passenger side just in front of the rear wheel. The pipes just unclip and there is one screw holding it in place. Advice from a ford mechanic was "change it quick and then you don't get too much fuel over the floor". So it was pretty easy to replace, however unfortuanely it didn't solve the problem.
Therefore next thing to replace was the plugs and leads. These cost £30 and were easy enough to replace with the aid of my dad's ramps (as it's easiest to unplug them from underneath the car). The assistance of second person is a good idea when changing the HT leads due to the location of the distributor on the back of the engine. Anyway changing the plugs and leads solved the problem, and now the car is running perfectly again.
Glad I didn't have to take it to a garage as they wanted £85+VAT just to diagnose the problem!
