Sorry if this is a long winded thread,but have a problem

i drive a 95 Classic WRX which until last Tuesday was going great,i then was low on fuel so filled her up with V-Power,Though had been told that v-power does not suit all cars About 1/2 mile down the road,it sort of died,then picked up,and was fine again,3 miles on she juddered then cut out,as if it had run out of fuel,but had plenty.. Started her up again drove fine for the rest of my Journey,about 40 miles.. so assumed i had picked up something from the bottom of the tank...

Then it got worse,the scoob was Hesitant,would pull back and even completely cut out,nearly causing a lorry to rear end me,as just died on me,even under normal driving it was jerky/juddery.. Took her to a garage where i was told its gotta be the coilpacks as does it while cold,but it was doing it all the time hot/cold..
So decieded on a process of elimination..

So have changes plugs,Fuel filter,checked all pipe work connections etc Now she drives a real lot better,but i still have a bit of hesitasion,though has not died or cut out,but when trying to give full beans or even half beans you get to 4000 revs in 3rd and its juddering though it does'nt cut out,when i change to 4th its fine,and picks up a dream.. never had this happen before,has anybody got any idea why this is happening,also my car runs and performs a lot better on unleaded,which is puzzling a lot of people as they tell me to run her on super,v-power etc,but since running on these i have had these problems,so dont know if connected or just a coincedence..

Any thought would be greatly recieved....trace x
