I've owned this GTi for just over three years now and, apart from the regular servicing and a clutch problem 18 months ago, it's never let me down... Until now!!
When driving, be it at a sedate pace or putting it through it's paces (I drive within the speed limits, honest officer!) The car will start jerking and spluttering like someone's thrown a spanner into it.
I've taken it to a mechanic (useless tit) who cleaned the air intake bits and the dizzy, which left it driving for one week, but now it's back to the same.. I've tried recleaning those bits again (No way am I paying ?60.00 for someone to put a bit of spray on my engine) but it doesn't work!
It's an intermittent problem, sometimes I can just hammer away at the pedal and it does exactly what it says on the tin, other times it splutters so bad that I have to drive it like an old lady and I'm taken over by dinky little Uno's, Rovers and, today, a 1.2l nova, with some sniggering little kid in the drivers seat!!

. The pride of my beauty is at stake here!
I will take it to a mechanic, but my experiences with them have always been bad ones so I'm hoping for as much advice as possible so I can understand the cause and, hopefully, get it fixed.
Any advice will truly be appreciated!
