Hi guys - i found out what the problem was - the exhaust was blocked
the last place i looked - i couldnt get the car past 40mph - so got angry and flored it - there was a big bang and the car shot off
the exhaust blew wide open - so if anyone is having the same problems look in to that 1st...
I have looked all over the web and i can't find anyone who sells them!
anyone know a place :) - so i can change them myself without paying £250 to Nissan!
nissan micra k11 cvt clutch brushes
Thank you :)
